Almost everything Google does outside of GCP, Maps, Search, and YouTube could evaporate for all I care. Google's problem is not that they cancel stuff, it's the everpresent need to grow revenue and embed annoying ads into more and more of everyone's daily lives. I'd love for them to cancel Gmail with a very short notice period.

The endgame for Google is every Google user loaded full of energy drinks watching ads continuously for 20 hours a day. Every lifestyle that's less profitable than that is something Google will eventually try to engineer away.
