Well to be fair even if you go full conspiracy theory or whatever an go insane to the point of blocking everything I doubt you are completely safe from anyone knowing who you are or what you do. In my country a few years back it was a big scandal because the internet ISPs were decrypting trafic and we're knowing everything anyone did on the internet as well as selling that date to ad companies. So I don't really care about this shit anymore cause I already know someone somewhere is already selling my data, I use an ad block just to not be bothered by stupid pop-up ads and that's about it.
