Using social media is far removed from operating your own publicly available social media server.
This coming from someone who is trying to get more mastodon usage in higher ed. Profs aren't the ones who operate these things. Merely getting the approval to get the project started is an immense task.
No, I'm one of those people that understand that a DE is not the OS. A DE is a component one can install, but doesn't have to, in order to have a fully functional OS. Most certainly one does not require Kate in order to have a Linux OS installed. I have thousands of linux machines I manage that DON'T have Kate installed.
Weird, because I only have Kate because I asked for it to get installed. It didn't come along for the ride when I installed KDE.
Paint comes on the MS Windows ISO (Or did), and with zero choice given, ever, MS Paint gets installed.
I installed MX Linux yesterday, and Kate was not installed.
I installed KDE on Freebsd a couple of weeks ago, and Kate was not installed.
I don't think any of that matters, tbh. Every user will have things to learn, once they switch to a new OS.
