Clearly Email is not the point of discussion here, as no one is building a business around it. It's Android with its app ecosystem, stadia, YouTube etc. Do you not see any problem with having effectively no support for these services?

Providing something for free is not a defense against anti-trust law.
The most famous example showing this, was regarding internet explorer, which was provided for free, yet anti-trust law effected it anyway.
