While true, in order to get Linux mobile more mainstream, you have to have great google compatibility just because of the sheer volume of people that have to use google calendar for sync with family and friends and/or have gmail as a primary email. That’s just a shitty fact of life. Baby steps.
However, indeed you are completely right that at the current time there are probably a very low amount of people wanting to use it right now that are completely reliant on google.
New year 2026? 😉
