Do we know whether bunny.net is any better? In the abstract, no we don't, but we're not dealing in abstracts, so we actually do because of where they operate. A real European operation (not an international company with EU presence but an HQ outside of direct EU jurisdiction) is by default quite a bit better at not violating GDPR, and runs the actual risk of being fined into financial insolvency (rather than getting a few hundred million slap on wrist that a multibillion dollar company goes "pff, whatever, let legal sort it out" to).
By virtue of Google's track record, and by virtue of where this new service is located, and the track record of EU based services with regards to privacy compared to their US counterparts:
Yes, we can _very_ reasonably assume both of those things.
Why do you think you know how it works? What do you actually know about Google that doesn't come from outside speculation?
That link says that a website leaked an IP address to Google. It doesn't say that Google did anything with the IP address.
I guess I'll say what I always say: Look at the public privacy statements for Google, or for a particular Google product. If you have any evidence that Google does anything different from what's in that statement, contact Google and there will definitely be people interested in figuring out what's going on and fixing it.
