I'm not even sure it would be illegal even if you just started using Javascript miners on every page as a condition for viewing the page - with or without notice. I don't think many people would consider it illegal to display an advertisement in a page "without authorization", or run an animated advertisement. That said, running these things without user consent isn't even the business model - they are specifically talking about allowing users to choose whether they'd like to do bitcoin mining or view ads, and they haven't released the product yet, so, basically the reason it "could be illegal" is because someone could take it and use it contrary to the intent of its creators in such a way that their actions have dubious legality. Should we also arrest all mask manufacturers because someone could wear one when robbing a bank?
