We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
Seriously though. You are sadly totally right there. “Works on my machine, so it must be user error.”
“First time doing this? It’s an easy fix bro: [unironnically links Arch Wiki, not even a specific page]”.
Or just: “Skill issue.”
