The people who are happy to read it do owe them a revenue stream if they want a website to continue.
To be perfectly clear I have no desire to see any ads, and I don't cos I block pretty much every last one (squid) but if there are sites that are worth reading, like from here https://news.ycombinator.com/item?id=25157722 well, author's got to make money for the time they put in.
Advertisers can die in rotting heaps, but they exist because people make them exist. They exist because you want free stuff.
All I hear is "I want free stuff". I'm not saying you should bleed yourself dry for them, would a couple of pounds/dollars a month (when you have paid work) to put rent-seeking ad men out of a job and to support OSS software development be so bad; would you even notice it?
