No you're assuming they can't use it. Why do you think they would give a shit? They can still use it because, again, only a tiny tiny portion of users are doing it so it doesn't poison their data. Even if it did, it'd just mean that the actions they take that are informed by said data would make things worse for users. Pointless.

You are literally accomplishing nothing and you're not even registering on their radar, because there's no way they'll ever even know that you give a shit. That's the most ineffective protest possible.
