You're really selling me on using Microsoft over Google here: If I'm using a product/service, I'd prefer that it stay around as long as possible even if the company decides that it's a failure. Bonus points for being a "cloud" company so that users are totally screwed the moment the company pulls support.
Yes, actually that's about what I expect. Not literally in a day, but fully do expect that in another year or two Google will announce that Stadia is going away and that in a few months it'll be gone. Games were rentals, not leased/sold, so they'll stop charging but you'll hardly be able to take your games with you. Saves might be Takout-able, so if you go re-buy the games you can keep playing... probably... if you even have hardware to game on...
In contrast, I've known people who ran MS software locally for months-to-years after it was obsolete/discontinued, and non-Microsoft software even longer (cue the classical story of the business that held on to their DOS software until Windows XP finally made it too painful to use).
Yes, but apply this to 90% of their new products. Google's planning in the current age is about as bad as Microsoft's in the 2004-2012 era.
