I do agree, that removing it would improve user privacy, however I feel that should be up to the user to decide on their own if they want or don’t want third party tracking cookies as it has been.
The alternative that Google proposed I don’t think it’s any better then what is was before with 3rd party tracking cookies. I’d say it’s worse since it introduces new problems while keeping old problems under a new name.
If everything goes through Google, no one has personal control and that’s what i’m against. This encourages what open source users should be against.
