AOL leads charge for MS breakup

Along with AOL, the three IT bodies named in the amici curiae are the Computer & Communications Industry Association, the Software & Information Industry Association, and the Project to Promote Competition & Innovation in the Digital Age, also known as ProComp. ProComp's backers include Oracle and Sun Microsystems.

Among the counsel for ProComp is former US Special Prosecutor Kenneth Starr, best known for his role as the government's special prosecutor in the Monica Lewinsky scandal that once threatened to topple outgoing US President Bill Clinton.

The 25-page brief covers familiar ground already trodden by parties supporting the DOJ's case, such as Microsoft's violation of US antitrust law as embodied in the Sherman Act and the company's harmful conduct towards its competitors, notably Netscape Communications, now part of AOL.

US District Court Judge Thomas Penfield Jackson ruled on June 7 last year that Microsoft should be broken into two parts, after determining that the software giant had abused its monopoly in desktop operating systems to stifle competition. Microsoft appealed the order, which the judge stayed pending the outcome of the appeals process. Both Microsoft and the DOJ are set to engage in oral arguments at the appeals court on February 26 and 27.

The brief also calls for Judge Jackson's conduct remedies against Microsoft to be upheld, which are also being stayed while the appeal is underway.

The core of the case, according to AOL's brief, is "Microsoft's use of a broad range of predatory tactics to maintain its existing monopoly over PC operating systems."

The filing argues that Microsoft's guilt has already been proved by the wealth of material drawn from Microsoft executives' conversations, interviews and e-mails quoted during the antitrust trial in front of Judge Jackson.

"This case is unusual in that Microsoft's senior executives spelled out their plan to monopolise in detail," the brief said. "[Microsoft's documents] spell out not merely an attitude but a clear recognition of the threat to its monopoly and a detailed scheme for suppressing potential rivalry."

The brief dismisses as "figments of lawyers' imaginations" Microsoft's claim that its behaviour in the market was designed to achieve economic efficiencies in its business. The software giant's claim that it linked its Internet Explorer (IE) Web browser to its Windows operating system in order to benefit ISVs (independent software vendors) is a "fictional version of history," the brief argues. The tying of IE to Windows was a central part of the DOJ's case against Microsoft.

The brief alleges that Microsoft's threats to cancel Windows licenses for PC makers who didn't want to install IE was "a naked threat to put OEMs out of business," since Microsoft was the sole source for the OS. "The forced inclusion of IE... wasted valuable computer hard drive space, degraded system performance and caused customer confusion," the brief continued.

By preventing competition in the browser and OS markets, Microsoft also "stifled innovation and limited the competitive potential" of companies such as Apple Computer, Hewlett-Packard and IBM since they were effectively prevented from installing non-Microsoft browsers on their PCs and weren't allowed to customise their consumer interfaces, according to the brief. "Similarly, by coercing Intel into abandoning research on software that could have helped other companies compete with Windows, Microsoft hampered innovation and reduced the threat of competition to its operating system monopoly," the brief added.

It's vital to curtail Microsoft's behaviour by splitting the company up, the brief contends, since the software vendor "is already expanding the Windows monopoly to engulf additional technologies that might present alternative platforms." The brief points to Microsoft's behaviour when asked to comply with court decrees in the past. "(T)he record here demonstrates that Microsoft does not take legal obligations seriously and cannot be trusted to comply with them," the brief said. "When the district court tried to enforce the 1995 consent decree, Microsoft responded by proposing to distribute a version of Windows that did not work -- and with a straight face told the court that its order required such a response."

The brief continues, "After more than a decade of antitrust enforcement scrutiny, Microsoft continues to use illegal means to short-circuit competitive challenges to its dominance. The district court properly concluded that it is time for those abuses to end."

Microsoft is "already tying Windows Media Player to Windows" and is pursuing a similar course with other software products including instant messaging, the brief contends. Splitting Microsoft into two companies, one owning the company's operating system, the other its applications including IE, would encourage both units to support non-Microsoft products, hopefully boosting the adoption rate of other operating systems, notably Apple's Mac OS and Linux, the brief argued.

The brief points to the break-up of AT&T, which unleashed "nearly two decades of innovation" and benefited shareholders and customers alike, as a possible template for Microsoft. AT&T had also claimed that it could not be split up without "ruinous results," the brief notes.

"Established principles of competition allow us to predict that the break-up of Microsoft will similarly inject competitive rigour into the industry, likely leading to increased innovation and consumer welfare," the brief states.

The software giant has butted heads with AOL before, notably voicing criticism over AOL's multi-billion US dollar merger with Time Warner, claiming it would harm competition. The merger was completed following the official go-ahead from the US Federal Communications Commission (FCC) late Thursday.

Earlier Friday, the DOJ filed its own brief with the Appeals Court in which it defended both Judge Jackson's ruling, as well as the judge himself. The software vendor is due to submit its response to the DOJ's filing on January 29.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
