I tried using free tier NextDNS on a network with 2 Samsung TVs hooked up and hit the threshold of 300k requests within a week. It’s mad how much data Samsung is collecting from their smart devices. Even when not using any features, the TV may stay with a screensaver and still send lots of data.

What you describe is to some extent existing in multiple countries. Basically the degrees in industries that lack specialists get more free slots whereas the others get less. As a student you can still start studying for a fee, if you don’t match the requirements (usually it is based on grades) but you can get to a free slot later on if your grades are good enough.

Why not make it free? At the end of the education cycle the student will get a job and start paying taxes. Isn’t that what society needs? Having educated people to do various jobs. Why putting that behind a crazy paywall?
