Enforced Obsolescence 

A more heavy-handed version of Planned Obsolescence usually employed in the high-tech industry, especially software. Consumers of a product are forced to upgrade through some new technology rendering an old one literally unusable, usually through unnecessary incompatibility issues.

Porting a game from the 360 to the PC, rewritten to require DX10 when DX9 was used originally and clearly runs the game, can only be Enforced Obsolescence.
