McCain is said to be advised by pro-software patent lobbyists. Ray Gifford, ex-President of the Progress & Freedom Foundation (a Washington 'think-tank' notably financed by Microsoft lobby proxy CompTIA), was speaking in a conference in Prague in February 2006 (see IP-Watch article "Industry Readies For Round Two Of EU Patent Directive") about the failed software patent directive with all the pro-software patent lobbyists (SAP's patent attorney, ACT, CompTIA, Microsoft, Siemens, etc…):

Microsoft’s McGibbon said EU Internal Market Commissioner Charlie McCreevy sees the patent directive as “fundamental” to Europe’s productivity and competitiveness. Later, PFF President Ray Gifford said fear of lost competitiveness is an effective argument with policy makers. Schmalz also raised the spectre of Asian software developers taking jobs from Europeans if measures are not taken to improve the European patent system.
Progress & Freedom Foundation runs the IPCentral blog, which supporting CompTIA's lobbying and even treating them as 'friends':
I wish the best of luck to Lueders and our other European friends as this battle continues.
It is not surprising, since PFF is financed by CompTIA (according to Wikipedia PFF's page and Archive.org):

According to the Sourcewatch's article, PFF seems also to be paid by Microsoft to write anti-open source articles, here is an extract of "The Enigma of Open Source Software" written by James DeLong:
In my opinion, open source looks like an idiosyncratic quirk that piggybacks on the billions of dollars that were spent on Unix rather than as a product of a real economic model. My view is that the open source advocates are pushing hard for preferences precisely because they doubt the sustainability of their model, and think that legal favoritism is necessary to keep it alive.
James DeLong was also present at the Prague conference with other pro-software patent lobbyists:
Despite SAP’s call for a bridge, some meeting participants fed distrust of the directive’s opponents. PFF’s James DeLong asked how the opposition got its funding, and whether it came from foundations. Schmalz replied that it came from open-source software companies. Speaking to the like-minded business audience, Schmalz also said that some industry representatives reported being personally threatened during the debates last summer.
