What happened?

Hi so I just watched a YouTube short saying that Unturned is dead because the developer hates modders and only cares about himself without going into any details. I found it weird and looked at the comments and everyone seemed keen on some forum drama about modders insulting Nelson's friends and getting the rights to their work stolen because of that, but with no proper explanation nor proof.

So I came here to see if there's anyone talking about this recently and can't really find anything. What happened and how long ago was it?
