The effectiveness of the access control is usually a factor.

If there is just a banner hovering over the actual text, and the extension merely removes that banner, than one could question whether there even was an access control in the first place.

As an extreme example, a Finnish court ruled that CSS (as used by DVDs a long time ago) was ineffective.

I agree that a banner or any over overlay is not protection - the content has already been delivered to the recipient.
