I don’t think it is people being possessive but rather people finding their value over the work they do (sentence ended up being weird but I hope the idea is clear).
So I see someone dedicating a sizeable portion of their life on a discovery and not being credited is the problem here. Otherwise it would be published in a journal anyway.

When your work is unimportant enough for you to not setup a local AI, just shut up.
