I agree completely, it is ridiculous and should be stopped immediately, but I don't see a way this problem can be fixed. EU is trying, for example after GDPR all these cookies became horrendously annoying. What you're suggesting will lead to clearer and possibly lengthier EULA or TOS documents but in essence we would still have to either agree with them or not use that service. While a lot of open source and self hosted options exist to replicate many of the services, but you can't rely yet on that for everything.

You can sure as hell double down on strict privacy settings and use a lot of privacy friendly options like librewolf, mull, private dns, nextcloud, matrix/jabber, VPNs, immich, better search engines, Open street maps, and OSes like arch and Graphene.
