@K_REY_C Interesting! I have not seen these videos, but I would hazard a guess that it's the discoverability thing.
New people coming to Linux does not know about the "app store" app, and for some reason people prefer to search online over just looking a bit closer on their screens. So instead of finding the store, they might search "how to install X on Linux", and guess what? All the results just tell them to use the cli! Because using the store don't need a guide, I guess?
