Well, i think i saw several posts about this topic popping up in the last few days. And posts questioning things like this one. I'm not sure. I think this is fearmongering. Other services know even more about you and they even harvest and analyze this kind of data actively... I bet your Facebook-friends also know who you are. So what's the point? True. We need GDPR compliance and to save as little data as possible. But if you want something anonymous: Install Tor or anything suited for that task. Don't write blog posts and spread FUD about this platform. (Or do it, but then don't be a hypocrite and also write about what reddit/google/twitter/amazon do with your ip and browser fingerprint)
