doesn't the modal "sign up for facebook" that cannot be dismissed take somewhere between 50 and 80% of your screen space? I'm talking of these "public posts" your users chose to share.
Or is this just my large font preference for vision impaired? Either way, it leaves very little room for text, sometimes none at all.
News flash: Dark patterns harm accessability, but you knew that. Good work.
Yes, I agree that the "Sign Up for Facebook" box is annoying. That's not my wheelhouse and not something I'm likely to have success changing. If, however, public content gives a forced login dialog, that sounds more like a bug that I can fix.
