The BSA should "keep out of the UK" and leave domestic rival FAST to fight the anti-piracy war on its own, FAST's chief executive officer Geoff Webster told PC Week last week.
His comments came after the Federation Against Software Theft lost yet another big-name member last week, with Microsoft choosing to throw its weight exclusively behind the Business Software Alliance.
Microsoft's departure from FAST follows that of Adobe and Novell early last year.
Webster hit out at the companies saying that in effect they were now "freeloading", gaining all the benefits of the work FAST does against fighting software piracy in the UK while contributing nothing to the organisation itself.
According to the companies, their departures are mainly due to the fact that the BSA is a global organisation while FAST covers only the UK.
Despite this, Webster said their reasoning was wrong: "Looking at software piracy as a whole, only 4% of the problem is imported. Companies such as Microsoft may have problems in countries like China for which they are right to be with the BSA, but it is wrong for them to walk away from the group which is the most effective in Europe."
Yvonne McLean, UK BSA chairperson, disagreed: "Software piracy is not a local problem, it's not a UK-specific problem. The advantage of the BSA is that it is not just based on these shores - if we keep out of the UK, who will represent the companies that we do but FAST does not?"
