My understanding is this:
It’s just the principle of AUR wrappers. Yes they are very useful, but anyone and their uncle can put a package in AUR name it whatever they want as long as it’s not taken. AUR wrapper makes it easier to install things without knowing much, but manually searching for something, finding it, and installing it involves conscious choices. Arch cannot be responsible for people installing malware from a software they recommended, that’s why it’s kept this way intensionally.
Imagine if yay/paru came with the os, or could be installed from pacman, then people would just recommend doing that to new users and then they might just install whatever and break the system a lot more.
Thank you. I have a family to worry about so can’t survive on ramen alone… But I’ll look for other countries postdoc and such. I’m a bit scared of moving somewhere I don’t know the local language now because of how things are going in the US, if something like this happens and I can’t understand their language I’d not even know the dangers.
