Sure, local models good and yes, there's no way we can trust Google.
We can be positive the entire motivation of Chrome is user behavior surveillance. There's not a nano-chance in all the multiverses that Chrome model is doing anything privately. They've gone to extraordinary length to accomplish this. It's not for free.
I don't trust them either, but the same Google makes Gemma 4 available to run as locally and privately as you want, and those models are pretty amazing for their size.
It is entirely about user surveillance as well as pushing their product on to their users because they have the install base. Google Chrome has become Microsoft IE6 in hostile user behavior.
