But how many users will do so? 1%? 5%?

Also, they will probably find that out, and the moment people do so, they become suspicious to state actors. I understand the rationale behind the work around you described; I just don't think it will be a huge factor. I see this elsewhere too - for instance, I use ublock origin a lot. But how many people world wide use it? I think never above 30%, most likely significantly fewer (or perhaps all anti-advertisement extensions, I think it most definitely is below 50% and probably below 30% too).
