So the current situation is:
MS didn't steal that song (no sane people ever thought it), BUT:
1) Using that song instead of another one is benefitting LBP and Sony, at least slightly.
2)The worst thing about that ad is not against Sony, but XB users, as it's misleading, only basic connection is free, but online gaming services aren't.
3)Third point is very debatable and subjective: the whole ad IMVHO has a vague LBP look 'n' feel.
4)Fourth point is ascertained and universally known and accepted but by a few die-hard ballmer-boyz: MS is EVIL. But this ain't anything new and is unrelated to the song.
