Supposedly it tones down it's activity while a user is logged in and waits for the machine to go idle. Another reason to have centralized performance monitoring.
What are they going to do ban math? That's all encryption is. Just because you block a few services isn't going to prevent anything from being encrypted. I can do end-to-end with just a couple of certificates. Are they going to ban PGP or TLS next? Is everyone going to have to install a Danish root cert, so the gov't can spy on everything?
When it comes to the internet... I'd prefer it to stay like the wild west. Least amount of regulation beyond something like net neutrality. People forget that the reason we have all of these "free" services is because of ads and that's coming from someone who hates ads. Every streaming subscription I have, I pay for the ad-free service. Let the people who don't know how to install a browser extension or change a few settings pay for these things for the rest of us.
