Re: No guilt at all
"I have little guilt for using a host file based adblock however, I understand the plight of these sites. There business models are being turned upside down."
Their business models were being turned upside-down 20 years ago. The time to start working on solutions to that problem was then. The fact advertisers chose to spend the interventing time on what amounts to advertising their claims that advertising is necessary to pay for advertising so you can keep seeing advertising should tell you all you need to know about the way the industry thinks and works.
Personally, my opinon is that advertising is an insidious social cancer that hijacks human emotions (needs, desires), human constructs (organisations and companies), and much of the human environment (most of what you see and hear) in order to do nothing more than grow and reproduce itself. That's why I have no guilt at all about using an adblocker. The irony of the fact that ~7 years ago it was the slow-loading ads on The Register that lead me to first install Adblock (then Adblock Pus, then later uBlock and uBlock origin) is just the icing on the cake...
