At the end of 2020 CentOS announced it would end support at the end of 2021, which sent shockwaves everywhere. Developers and users alike rejected it — even CentOS's founder started the Rocky Linux project that same month to build the next CentOS. Red Hat immediately adjusted course, publishing a post on its official blog on January 20, 2021.
Plenty of webmasters wonder how much site ads really earn. I was curious too, but few seem willing to share — maybe because income is a sensitive subject. The big players can't be bothered, and those doing poorly are embarrassed to admit they make a few cents a month. I have no such shame, so let me lay it out for other webmasters: how much can you actually earn running Google AdSense?
