People have the right to blame something for doing something wrong. If McDonald's burns my burger, I'm going to blame them, even though I can choose to not go there.
It would be a rather odd turn of events if they burned your burger without you ever visiting the place, though.
I fear that their approach is likely to just create an arms race, though. The same people who, for whatever ill-considered reasons, disabled it once will do so again. I'd rather control it as a user.
Because, honestly, I only ever see this used to keep me from having my password manager manage secure passwords, which is just obnoxious. These are usually the same sites that ban things like spaces in passwords, or cap you at 10 characters.
