Are you saying Google should hand over the IP addresses (...) I prefer Google having my IP over Google and a million other companies having my IP.

What I prefer is not making the entire Internet into something that only works because Google+Cloudflare work as this giant man-in-the-middle / proxy for everything out there. If Google actually makes this service the default behavior on Chrome that's where we're going, think about it, hosting providers, datacenters and ISPs will simply assume that to reach any website you'll be going to Google and Cloudflare's servers, then they'll prioritize traffic to those, enter into special agreements and obliterate net neutrality in a new way.

This can really spiral-down into a situation where you can't even reach websites if you don't use that service very quickly. I bet both of companies will push for that scenario because if they do then they'll become the middle man and be able to tax everyone on Internet traffic, strong-arm ISPs and push their cloud hosting offerings with cheaper prices and advantages that other provides can't match because they aren't on the middle. Just think about how much money CL can do selling "proxy / near edge advanced caching for websites" and stuff like "if you host in Google Cloud you'll get that caching service at proxy level for free" and then they proceed to place even more servers in your ISP's datacenters to cache said content. ISPs will be happy as this will limit the amount of peering and "outside traffic" they've to do and CL+Google will own the Internet even more.

this shit will fly in the eventual antitrust case that this will trigger

Yes the EU will be very happy to go against Google on this one as this look a lot like a classical case of dominant market position abuse and an anti-competititve scheme.
