If the features hadn't been useful, it wouldn't have worked. Are you seriously going to argue that their strategy – their explicit strategy – was not incredibly harmful to innovation and competition? Also saying they "invented" XMLHttpRequest is a stretch. If I make a browser with a nonstandard rot-13 function, did I "invent" JSRot13?
