This isn't always easy and a lot of software on flathub is old-ish, so people tend to open up permissions since it's difficult to implement all these features properly. In my experience people will rarely stand in your way if you try to improve a package.

People need to be paid. People want benefits. People need to be taught how to edit. Children need to be taught how to research. People need to be brought together to figure out where the site and the tech is going. People want to feel safe participating in their community. If Wikipedia had only ever been "server costs" it would be nowhere close to what it is today.

I would be surprised if responsible Valve staff would agree that this is not something they should fix at some point.

And as you can see in the post, this is not just code, it's also people being hired to do docs, planning, conferences, community, design work, web dev, things that are rarely done well in open source because they are hard and people can get paid for them elsewhere.

I think it would be fair to say that the club as a whole has become more open about that, I think that's more owed to a lot of folks driving initiatives feeling like the walls are closing in on them though and I can't exactly fault them for that :)
