IBM accused of mainframe monopoly

Note that it's a competitor that is complaining, not customers.

IBM accused of mainframe monopoly - Tech News on ZDNet: "A complaint alleging that IBM has abused its position in the European mainframe market was filed with the European Commission on Tuesday. The complaint from T3, a small US supplier of mainframes, said IBM has 'a history of abusing its monopoly power in the mainframe industry', according to a statement from T3. IBM is accused of engaging in a range of anti-competitive actions, including 'preventing the sales of competing mainframe hardware products by tying the sale of its operating system to its mainframe hardware'. IBM is further accused of 'withholding patent licenses and certain intellectual property to the detriment of mainframe customers'. In its statement, T3 said it sold IBM mainframes but then moved into selling its own products, the Liberty line of mainframes, first developed by Amdahl Corporation, which itself is now part of Fujitsu."
