It is though!

Often news websites use the user agent to detect e.g. the google crawler, and allow google to index the contents of news articles; but then throw up a paywall when anyone with a normal browser shows up.

I recall some news websites tried to threaten people making browser extensions with the DMCA/CFAA as they considered it working around their copy protection to illegally gain access to their content.

Source? I spent two minutes looking and failed to find anything like that, hardly an exhaustive search though.

Hard to argue a user agent could be DRM though, considering it's a string I the user send to the website.
