If you want to complain about something, complain about the completely pointless fragmentation of the Linux ecosystem that pretty much mandates "curl|bash" to ship software for "Linux."
The problem is tools -- plural. Users think "I have Linux, where do I get the Linux version?" You have to provide arcane instructions for how to add a package repository on Every. Single. Linux. Distribution.
Or you can script it and users can run a command. Still painful, but less so for the user.
As far as the distributions themselves go: they are harder to get software into than the Apple App Store. The rules are arcane and the docs either barely exist or are on wikis that have not been updated in over a decade. The whole process is unnecessarily arcane beyond belief.
