Reminds me of the Creative debacle when Vista was launched. Creative deliberately crippled sound cards via the drivers to force punters to go out and buy a new card. Things got really messy when some guy (Daniel_K) discovered what they had done and released unbroken drivers. Creative accused people of stealing from them by using these fixed drivers!
"According to a report by DailyTech, Creative’s Vista drivers for Audigy series sound cards leave off a number of features that were present in the Windows XP drivers. Among those are DVD audio support, a software equalizer, CMSS stereo surround effects, THX options, and Dolby Digital/DTS decoding. Daniel_K’s drivers re-enabled these features, but Creative’s statement suggests the decision to not offer them in Vista was intentional: “If we choose to develop and provide host-based processing features with certain sound cards and not others, that is a business decision that only we have the right to make.”
Both Creative’s move and the phrasing of the cease-and-desist note itself angered a considerable number of users in the company’s forums—enough to fill the thread with over 230 pages of replies—and led sites like Slashdot to report on the news. In the note, Creative states bluntly, “By enabling our technology and IP to run on sound cards for which it was not originally offered or intended, you are in effect, stealing our goods.”"
