Some of the services you mentioned are already very irrelevant:

* Fitbit -- no explanation necessary

* Google translate -- I don't know about if people use their APIs, but for me personally, I have not used translate for a few years. ChatGPT has been my go-to.

* Google Pay -- it has a smaller market share than Samsung Pay.

Then next tiers of services -- they are doing ok but there are plenty of competitors in the field:

* Gmail, Drive, Docs, Groups, Forms, Cloud, Flights, Fi

I even use some of them, but I really don't care if they go away.

Life gets a bit more difficult if Maps, Chrome and Android are gone all of a sudden. Maybe we'll be back to using Garmin. Heck, I love the idea that everybody uses Nokia, Bing or Garmin for navigation, and we actually have a decent website -- like the Yelp or Zagar in the old days -- for restaurant reviews. I still see "#1 Rated Zagat" stickers from near two decades ago at many restaurants.

Anyway, personally, for the vast majority of the things listed here, I don't see them going away being a bad thing that would even affect as many people as you think.
