> Funny how in reality it's not how open source works.

Let me copy the full sentence, with the part that you conveniently truncated: "That's how open source works: if you use an open source project and it has a bug, you can fix it and open an MR. If the upstream project doesn't want your fix, you can fork. Nothing forces the upstream project to accept your contributions. When they do, they take the responsibility for them (to some extent, as in: it is now part of their codebase)."

Can you explain to me how this is wrong?

> I'm getting tired of your rants and tangents

How is that a rant? That's almost by design: I make my code open source so that people can benefit from it for free under some conditions. Take the billions of computers running Linux. Which proportion of those are run by people who actually contribute to Linux, do you think? As a good approximation, it's ~0%. Almost all users of Linux don't contribute to Linux. It's a fact, not a rant.

Nowhere did I say that people should contribute.

> Ho many package managers and package format are there?

Who cares? If I want to create a new package manager with a new package format, why would you forbid me from doing it? That's my whole point: people are free to do whatever they want. Are you saying that I must use Flatpak instead of my favourite package manager because you have decided that it was better for everybody?

Why do you stop at package managers? In your view, isn't having different OSes is wasted/duplicated effort? Should we all just use Windows because it's your favourite and you don't understand why other people may have other preferences?

> Sorry, I'm not privy to those voices.

My point is that whenever somebody says "it's stupid, we should all use X", my answer is always "If Y, Z, A, B, C, ... exist, it's because other people, for some reasons, don't want X. Because you like X doesn't mean that everybody should like X. I see how it would be convenient for you if everybody used exactly your favourite system, but the reality is that we can't all love exactly the same things. Hence there are alternatives. Diversity is good".

Diversity is good. I don't say that Flatpak should not exist. I just say that whoever wants me to use Flatpak is fundamentally missing something.
