Alright, so alot of people are against the idea of a website using 60% or more of your CPU while you are browsing. Listen though, you cannot complain about display advertisements and pop-ads then complain about the alternative that is presented in front of you. The mining is quite a cut for websites as it doesn't make nearly as much as any form of advertising but they are providing you a cleaner browsing experience because advertisements aren't littered across your screen. I use a web miner, I have it set up on my server and is mining a coin called Bytecoin, it is a huge cut from the profits I was making on display advertising but I made the cut because my users wanted them gone. So I have it set to 60% mining which in theory shouldn't affect you that much unless you are running a bunch of crap on your computer at once which is on you.
I think that it is the future of advertising and will be a better and hopefully in the future much more widely accepted method of advertising because if you get rid of them all then you are going to be left with services that are going to require subscriptions in order for them to make money to run.
