No, what was minio is now aistor, a closed-source proprietary software. Tell me how to fork it and I will.
> they wanted to be the only commercial source of the software
The choice of AGPL tells me nothing more than what is stated in the license. And I definitely don't intend to close the source of any of my AGPL-licensed projects.
So fork the last minio, and work from there... nobody is stopping you.

The fact that new versions aren't available does nothing to stop you from forking versions that are. Or were - they'll be available somewhere, especially if it got packaged for OS distribution.
