Captchas for website access (not signups etc) seem to be mostly about preventing scrapers that are not from major companies and spying ofcourse. I don't see how they are in the interest of the site owner. It is just an annoying default for no fee caching/CDN by Cloudflare etc. If I would have to pay 10c to visit a website I would like it to "burn up". Most websites I visit I don't support in any sense.
