I think the landscape has changed with those hyperscalers outcompeting open-source projects with alternative profit avenues for the money available in the market.

From my experience, Ceph works well, but requires a lot more hardware and dedicated cluster monitoring versus something like more simple like Minio; in my eyes, they have a somewhat different target audience. I can throw Minio into some customer environments as a convenient add-on, which I don't think I could do with Ceph.

Hopefully one of the open-source alternatives to Minio will step in and fill that "lighter" object storage gap.
