So question. If google puts the tracking in chrome like they are supposedly going to do. The vpn won’t protect you (assuming you use chrome)… they don’t need to snoop on it, they already have it from another source.
No VPN ever protects you from ad-tracking. Like literally none. That’s not what they are for. VPNs protect you from someone intercepting your traffic on the way to the websites you want to visit. It protects you from malicious public wifi or a malicious ISP. It does not anonymize you in any meaningful way.
Addition just to explain: Google is tracking you on the website you visit, with the help of said website. So no matter whether you use a VPN or not, if you visit that website with or without a VPN, with all the fingerprinting that happens nowadays, they would probably just get a datapoint like “Oh, user X just moved from home internet to VPN” and that’s it.
Like it literally does nearly nothing if you don’t ALSO do 100 other important things to anonymize yourself. A regular user has nearly no chance to stay anonymous the moment they use a regular browser and a VPN would not help them at all.
