Google does (did?) have as part of their core values “do no evil” so that might be best…

Which ever is offering most value (price for speed) in Fiber is who I’d go with.

If is “DSL” or “cable” then I’d give a serious look at Starlink…

If SL isn’t an option then probably go with AT&T…UNLESS Google’s offer is their own lines…if I recall though Google is rides on other’s network and in those cases you always want to get service via the parent network.

From back in the day I recall it labeled a T-LEC where phone companies are required to sub contract out a part of their network which is reserved by law for smaller companies to help fight a monopoly.

I dealt with this with CenturyLink when we had T-1 lines from them.
