They're specific to Linux distribution families, so they don't really apply to those who are running Android or iOS. Also, getting your app into repository isn't really easier than getting it into app store (see https://wiki.debian.org/DebianMentorsFaq#How_do_I_get_a_spon...) and good luck if you're trying to make money from the app.
I thought the original subject was that there's too much gatekeeping. Or is there just double standard, so that gatekeeping is good for Linux distros and bad for commercial app stores?
