So does Wikipedia. And at one point, I was able to download the whole thing on my computer because I was online only for few hours a day. I'm not seeing Wikipedia asking to disable any adblockers.
Wikipedia is a non profit and runs on donations. Static text vs YouTube scale service are also very very different in costs. That tutorial on internet is free, I can download the whole thing on my computer, why is that 5 years university degree program charging fees?
