I would argue the Tor example is not a valid comparison. Tor is a very complex system. It has a vast attack surface for holes, especially if you ignore boundaries like assuming there is a globally omniscient adversary.

Contrastingly, websites sanitizing inputs has been done for quite some time; it is hardly new, difficult, or complex. It's fundamental. I would guess most people's answer is that this is not a sufficient effort to protect privacy or security.
