Re: "In the 1990s, MS could never have been as stupid . . "
That is probably a significant part of the issue. Everyone remembers an MS that was lean and executed rather well. Not everyone realizes that when MS was a lean, mean fighting machine, it's because there was competition.
Where does MS have competition in the OS space now ? Nowhere. Ergo, no need to pay attention, got fat, got sloppy, got childish. Is now more interested in bling than functionalty.
And what can we do about it ? Zilch. Nobody is going to migrate to Linux because that is a functional nightmare for a company of just about any size.
So we bend over and take it, and MS knows we will.
