There's no prerequisite on having a popular Medium blog, Twitter, etc for having lots of users. Applications have a large network, but little media presence.

Also, you're never going to get any network if Apple never approved your app in the place...

I mean you could also say "If you get thrown into jail unjustly and have nobody to advocate for you that just means that nobody cares for you at a person" and be right in the same way - that does not mean that this system is particular good and everyone should be proud of it.

Polemic metaphors aside, I don't think the relationship you propose (quality app > network > you get help) is very consistent or reliable. Say I make an app for soccer moms with millions of users - do you think I would get significant Twitter support from my customer base if my app went away? Conversely, don't you think I can get the radicalized 50 customers of my pro-genocide to scream very loud on Twitter for weeks?

This does not even touch on founders/devs who want to stay anonymous for whatever reasons and a lot of other edge cases. It is a shitty system.
