This is kinda funny, but what is a better alternative for new projects on Linux?
I will say that though, it's probably not rational to be okay with blindly running some opaque binary from a website, but then flip out when it comes to running an install script from the same people and domain behind the same software. At least from security PoV I don't see how there should be any difference, but it's true that install scripts can be opinionated and litter your system by putting files in unwanted places so nevertheless there are strong arguments outside of security.
Open build service [1] / openSUSE Build Service [2] might help a bit there though, providing a tool to automate packaging for different distributions.
