The objection seems to be that this is automatic, with opt out, instead of with opt in. Another commenter makes the point that the opt out button is difficult to find. Those are the issues you should address.
Anybody know where the fuck the opt out button is? I literally can't find it on mobile
Edit: For anyone else struggling to find it, look for the box with the heading "Profile URL". There's a link in the upper right corner of the box that says "Visibility Settings". It's light grey text and kinda hard to notice that's a link.
Just for anyone else, if you're forcing users to opt out of something like this it should be a BIG BUTTON AT THE TOP OF THE PAGE.
