Ask HN: What does an alternative to Play Store/Services need to be successful?

I mean, set aside the Apple Store and the Google store (and the abomination that is the Windows store) all the rest (Linux and Windows before the latest) worked just fine downloading programs from the publishers.

[0] Where you can find tens or hundreds of similar and/or similarly named apps, mostly crap, or spin-offs, usually without a proper way to understand what the app actually does (or if it is the one which you actually want), if it works, etc., so that you have anyway to read online reviews, consult the publisher's site (if any) for reading the docs (if any), to have (if any) support, etc.

This can be a good starting point
