What makes you think the contractor didn't share the code? Or do you mean didn't share the work to PC? Generally if it isn't in the contract it may not have made sense for them to also make it for PC. It's always quite a bit of work supporting 2 schemes.
Sorry if I was unclear. You usually don't inspect the install scripts for official packages since you put the trust in the official team. You don't trust(or at least shouldn't) AUR packages, hence you should inspect the install script for those packages. I don't really see what the alternative would be.
So what would the alternative be? If the resources or desire don't exist to make a package official, how else would you install it?
I have been quite happy with the majority of Asket's clothes. I originally found them when looking for more environmentally friendly options.
Huge respect on standing one's ground like this.
