But essentially we actually heavily encourage copyleft licensing. Copyright is different then copyleft (at least from my understanding - but maybe I need to reword the sentence you quoted?)

Pretty much any type of "open" license is allowed except for CC-ND, because "no derivitive" sort of kills the spirit of our collaborative nature of allowing our projects to grow and evolve.

In short, I "own" the VPS, but I am trying my best to make the platform belong to the community, while I simply act as a steward of the commons. I back up nonsensitive data publicly to Codeberg, and share actual backups with other admins. The goal is to have the community outlast any one individual. If anyone ever wants to, they can essentially copy the platform to a new VPS and Domain, and continue the platforms operations.

In practice, there may be a few hurdles as I am inexperienced and still learning - but hopefully the systems and operations will evolve with th community if successful. I want the platform to be a commons, not "belonging" to anyone - but stewards that may come and go. Outlasting me or any other admins. The goal is to diversify control and decision making as much as possible, allowing the community to self regulate/govern, but obviously in these early stages we can't do that without members.

Hope that answers your questions, and we are always open to feedback. It's tough getting a community off the ground, and we are just a couple of individuals who are passionate about the idea.
