Apparently there aren't a lot of people here that know what the word "irony" means. Perhaps the word you were looking for was "hypocrisy"?
That out of the way, none of these tech giants ought to be able to call any of the others anti-competitive with a straight face. Microsoft, Apple, Google, hardware and software manufacturers, etc., are all doing things that one might call "anti-competitive," and it's sort of hard to take Microsoft seriously when they make claims like this. Perhaps they're bitter that they've been slapped with violations time and again over the years - maybe they just want to make sure that if they can't get away with it, no one else will be able to, either?
