People will care about that as much as they care about ceasing to use websites that are hostile towards them: pretty much not at all.
The entire ad-blocking concept shows that people will do anything to continue visiting a website they are desperate to consume no matter how user-hostile it might be.
Also, this "No-Tracking" pledge seems like a thought experiment that only considers the rare website with more or less drop-in alternatives. So, maybe just general news and some brochure info sites?
I guess it's possible at any moment in history to say that nothing will change because nobody cares. There will always be some truth to that.
But I feel like we're reaching some sort of tipping point. 200k+ people just signed up to a new social network whose only real usp is no tracking.
I don't know what a drop in alternative is so I can't answer your question, but if your assertion is that generally speaking sites need to allow their users to be tracked I would disagree.
