Never connect your monitors to the internet.

Then hack them.

My television sending me to prison wasn't exactly the dystopic future I had imagined but it will do.

You can do it yourself, but the actual crime is if you tell someone how to circumvent it.

Don't connect the "smart" bits to the internet and just use the screen. No one would know. I expect it is small and/or crappy though.

DRM is for restricting access, not guaranteeing constant mandatory access. I think it would be a gray area if someone disabled the ads.
