It’s so they can track you better. If you’re in the US and using a Chromium based browser, so long as you don’t view “adult content” they usually don’t pop this up. But they can’t track in Firefox, and because of GDPR, they can’t track logged-out users in the EU, so it’s all about the money. I use Vivaldi and a VPN to watch youtube, works mostly fine.
