> What makes you think that somebody's going to actually read the site's warning (...)? If they don't already care enough about web privacy issues, they're not going to take the time to read about them now.

If what you say is correct (that users don't care), they'll just click on Accept, right? And you have their consent. You've given them the option to make an informed choice. Your duty has been performed.

> Third, the regulation completely forbids a potential business model built around targeted advertising.

It forbids potential business models built around targeted advertising not based on visitor knowledge and consent (so it forbids business models that wilfully violate the privacy of site visitors without their knowledge, and without their consent). Again, if users don't care (as you point out), the gaining of consent isn't going to be an issue, so these business models will retain their viability.

So given your statement that users don't care about third party tracking or profiling, none of what you outline are really issues.
