Normally you'd just run sudo apt install ...
but in this case you are adding a new repository so you have to follow the extra steps of adding the signing key and so on first.

I agree with everything you say but it's there for those who are interested.
Fedora Core. It had so many problems updating. That would have been in the mid 2000s so it may have improved since then.
Are there any programs that can animate a cat to chase my mouse across the desktop?

Or you could switch Manjaro to the unstable repos which mirror Arch
I'm looking forward to Plasma 6
It wasn't on Linux on but on a Vax Unix machine in the early 90s. We were an IBM shop but the accounts department got a Vax to run their new software. Obviously we were expected to look after this little box with no training. Things went quite well until it started to to run out of space. I found a huge file called vmuniz iirc and couldn't see anything using using it. The file was deleted and the job was done. Until we rebooted.
Plasma definitely. Xfce is second.
I think it's mostly do with the carelessness of the devs. They've let their certificates expire multiple times (and suggested their users put their clocks back as a workaround) and DDOSed the AUR a couple of times by accident. To be fair, I haven't heard of any foul ups in a long time so maybe they're being more careful now.
At least you can turn them off!
It doesn't require it but it is often easier. It's also alien when you're new.
