I think a website using my hardware while I am visiting the site (keep in mind it doesn't continue to use your hardware when you exit the site), is preferable to seeing dozens of advertising banners offering countless ICO scams, having website "news sites" that sell news articles for premium dollars making it hard to determine what is fact and what is just another scam being paid to promote, having popups, pop unders, 10 second ad delays while I am forced to view ads before reading content, modal popups and the countless other gimmicks that have been used in advertising.
