How is maintaining a local block list opting out? It certainly doesn't seem to have legal force.
Presumably we have different definitions of opting out. I was thinking more of the DIY type. It's certainly more reliable than to trust the people you don't trust not to track you because you tell them not to.
Merging behavioral analytics like “people are still using this feature” and the more creepy type like retargeting ads that follow you around seems to be at the root of this.
If you use a service, why would you expect them to not know you used the service?
It makes tons of sense to be concerned with giving them PII or access to your other habits. But you’re upset that clicking a button on someone’s website informs that website? Combining benign behavioral analytics in criticism just serves to degrade real privacy concerns.
