The irony is that anticompetive behavior usually means competitive behavior but being the one that wins, as OP's examples show. OP even went wonder as blaming Google for Talk, which is mostly famous for being the last major service to disable XMPP after losing marketshare to competitors who already did or never supported it. Before Google, Apple and MS went head to head with the same anti/competitive techniques as each other but since MA one Apple got to play the victim.
