To me, this is like the left-pad incident and npm. There was a vocal minority who denounced npm for looking after the greater good, maintaining continuity and transferring the project to someone else.
In this case, since the author also deleted the project, the proper way to maintain continuity for the sponsors seems to transfer it to the new community of folks who are interested in maintaining the project. Sponsoring the old deleted project does nobody any good.
Personally, I don't see anything wrong with what OC did.
