An exceptionally well explained rant that I find myself in total agreement with.
I’d just finished migrating around 70 Centos 6 machines to Centos 8, a month ahead of them killing the distro that was supposed to last until 2028. We went with Rocky, but the problem is the same as Alma’s.
Fortunately both companies seem to have pretty well developed plans for coping with this, and no doubt Oracle and Amazon distros will too, so no need to jump ship yet.
That said, we’re also considering a debian shaped future, at least in part. There’s absolutely no way we’ll sign up for Rhel accounts. Not because they’re expensive, but because decisions like this undermine our trust in them as a business partner.
