beyond trying to kill the app via the task manager

Which is exactly what I said, just in shell commands because that’s quicker for me. Except pkill steam kills everything containing steam in the process name, steam is a little bitch spawning a lot of them. Quicker.

What you said sounds like mystic gobbledygook to me.

“Task manager” is not some fundamental term either. Someone who hadn’t use Windows, if there were many of such people, wouldn’t know that it’s a GUI application listing running services and some of the processes.

Mass Linux adoption is still far out of reach for the average user.

If you are going to measure it by what advanced users are used to not being immediately understandable for others, then it is.
