The article is a rather hot take in today's climate. Not only that, but leads out with the most flimsy observation of laws around selling homes. What?? Anyways, moving to saas is like the west outsourcing all manufacturing. The skillsets go away and don't usually come back easily.
I'm using Debian Testing with KDE, after using Ubuntu with KDE, and it's basically just some lack of polish, and I also sometimes miss the PPAs. (I understand that it's technically possible to use software from Ubuntu PPAs in Debian, but as I'm getting older, I prefer officially supported ways of doing things, so that I can stay on the happy path as much as possible.)
So all in all, not much of a hurt, for me at least. My home server integrations, my software and my games work just as well.
I think that Debian is lovely, but as a person with a hojillion scripts and configs, I don't know how Debian and Ubuntu have diverged over the years in terms of filenames, paths, package names. etc., and I'll have to find out (for example, Ubuntu's /etc/cloud/cloud.cfg.d/ vs Debian's /etc/network/interfaces).
I was also going to mention ufw, but I see Debian ported it, so that's one less concern!
Debian is my choice too! I run Debian testing and it is great! I have up to date packages, a ‘rolling’ release and now even Firefox straight from Mozilla
