> they actually played a positive role back then
Stop living in the past. Do you just want to wallow in self-pity about what could have been or are you actually upset about real problems that are fixable?
Apple is halting progress of web standards right now. Apple is locking in users into its closed ecosystem (good luck trying to develop for iOS without macOS). Google and Facebook are "embracing, extending, extinguishing" the web (AMP, Instant Articles, PNaCl, etc). Even the W3C has bowed down to the copyright industry with proprietary window dressing in the name of DRM.
Not everything these companies do is evil, the attacks are far less orchestrated than those carried out by Microsoft back in the days, but they're happening and they're here.
If you just want to hate Microsoft for nostalgia's sake like the grumpy old vet who still can't get over how the US lost in Vietnam, that's fine. But don't pretend you care about principles if all you can do is hold a grudge against what was and don't give a fuck about what is.
