Doesn't Google claim they don't read your emails?
There's plenty of reasons to drop Google thought. They barely improve old products.
They probably try to force us to use their products: I think you can't use your own assistant with a wakeword. On my pixel watch 1, using a calendar other than Google's sucks. There is almost no useful wearos apps (sure, it's the devs jobs but Google could bribe them or something). A lot of great wear os apps would benefit everyone.
I'm still pissed that they want a monthly subscription for the sleep tracking with the Google home thing... That you buy with your own money.
