They've done it for the last 15 years. People are now used to it so It's not entirely our fault.
1- It's hard to get money from people when you've been giving away your product for free for a generation.
2- Your product needs to be worth what you're charging or people will go elsewhere.
3- Blocking Ads is just as much a security decision these days.
So the old news media need to produce a decent product and somehow manage to get people to whitelist them or pay them. Hijacking their machines isn't a long term solution. I'd argue it's not a short term solution with the many implications and fluctuating prices of what they're mining. The Telegraph gives you a bunch of full high quality articles and a quarter of some others for free. To get the rest requires subscriptions. This model is decent and currently works.
