Package managers was one of things that I had hard time adjusting to when I first adopted Linux, since I was so used to just searching for software on the internet, downloading, and installing it when I was using Windows. Now that I’m comfortable with a package manager, I find the Windows experience of installing software to be so much worse. It’s so much nicer to just install software using one or two commands in the terminal.
Considering there’s basically no chance of fucking up the gorilla, I don’t think you’d have to worry about the ethics of the situation.
