Regardless of how you feel about Burnt ... he made that facebook page. He spent money advertising it. Probably close to $500.. if not more. He got all of the old school war2 players there. He invited the new ones. He added nearly all of the content.
It has value. He put value into it. Taking ownership without permission from the owner/creator is called stealing. That facebook group does not belong to you. It never did. Give it back to Burnt.
Well, I don't know who is the owner (primary owner) of the page, but what I have to say:
Burnt doesn't want to act together with other war2.ru admins, he opposes himself to others. He also uses his onwership for issue ultimatums against others. As happened with youtube channel belongs to him.
I'm very happy we have official war2.ru site/server/discord resources, the main advantage is these resources are being managed by serveral different people who respect each other and that guarantees some stability from someone's emotional impulse.
The problem with resources (like FB group/page, youtube channel) belongs to Burnt, we can't consider them a part of our war2.ru project, we can't invest our forces into these resources, as we can loose them any moment if Burnt decides us unworthy to remove our partnership for some strange reasons.
About ethic side: I think the question is not about the owner, but about people who spent their resources/time to promote/advertise the page.
If you created the page some years ago and then do nothing with it, and other people used to make it popular, you don't have moral right to consider it your own page.
I'm not about Burnt now, I don't mean he didn't pay attention to that page, I just don't know, it's common example.
