Where did I say any of this was ok? I'm saying you simply can't trust them. You can't expect to cost something to someone and trust that they will keep doing that forever. A business need to make money...

They didn't over G Suite legacy. Sure at least if there's ads you know they may make a bit of money, can you trust it's enough to cover what you cost them? That's a whole other story certainly, but for sure you can't trust that if you literally bring no monetary value for them.

> this shows just how you cannot trust anything from Google.

I'll again correct you, can't trust anything free.
