FWIW, I think Google has been turning things around for their paid services. I've had to contact Project Fi customer support a few times, and found it vastly superior to all previous experiences with telcos. They're also probably getting a ton of experience in dealing with enterprises thanks to GCP.
With that said, this announcement doesn't look like it has any relevance to regular consumers. I'm gradually migrating as many things as possible away from Google, having realized that I'd have no recourse if they locked me out my accounts. Their TOS [0] says services can be terminated at any time. I'd feel a lot more comfortable if we had a guaranteed grace period for migrating away upon your Google Account being terminated. IANAL though, so maybe I missed something?
