This is after MinIO asserted that Weka had also stolen their AGPL-licensed code, showing that they extracted binaries from the distribution. They forgot that that 3-month old (unmodified) version was still Apache licensed though.
MinIO generally don't seem to consult lawyers often. They haven't even set up copyright assignment / CLA immediately after switching the license, so technically they are also incapable of selling AGPL license exceptions just like everyone else.
I've done my best to keep MinIO away from most infra I manage, not because of legal concerns but because it was kind of obvious they'd eventually go full scorched earth and either drop images or the source code distribution all together. Maybe now we can all move on to a fork, or SeaweedFS, or Ceph, or literally anything else.
