That kind of behavior stems from leadership, though, and the MSFT we've seen post-Ballmer has been dramatically more aware of its position in a diverse marketplace (vs. attempting to own the entire market). This kind of thing is especially apparent in interoperability -- Office on the Mac is currently as good as it's ever been; I never need to switch to Windows to get something done. Sharepoint (which is awful) now works properly on non-Windows platforms. There are excellent iOS builds of the Office tools. None of that was conceivable under Ballmer. So yes, I'm old enough to have lived through all the things you mention, but I have also noticed a distinct change in MSFT's behavior in the last 7 years. I see this kind of browser tomfoolery as a return to the bad old days, for sure.
