Fair points, although the fact that Google is offering this product makes your point about violating the privacy of users a bit moot (in this particular instance...not the solution in general).
You could still browse the web with Ghostify (or µblock…), and only load the Contributor tracking code when you want to support an article.
That would both minimise Google's tracking and prevent you from accidentally contributing to crappy link-bait content. Basically a copy of flattr on Google's infrastructure.
