That's the open source model. It's entirely predictable that if you provide software at no cost that is capable of running 100PB clusters, that some people will and you won't get paid, because those are the terms that you set.
It's fine to change your mind, but doing it in this way doesn't build goodwill. It would be better if they made an announcement that they would stop creating/distributing images on some future date; I'm sure that would also be poorly received, but it would show organizational capacity for continuity.
If I'm considering paying them for support, especially at the prices quoted elsewhere in the thread, I need to know they won't drop support for my wacky system on a whim. (If my system wasn't wacky, I probably wouldn't need paid support)
There are a few challenges with open-source projects that want to also be commercial entities.
One is obviously knowing what you can add-on that people will pay for; support, for one, but people want more features too. What could minio have built on top of their product to sell to people? Presumably some kind of S3-style tiered storage system, replication, a good UI, whatever else, I'm not sure.
The second is getting people to actually know that that's an issue. I work for Tigera which publishes the Calico CNI for Kubernetes, and one of the biggest issues we have is that people set up Calico on their clusters, configure it, and then just never think about it again. A testament to the quality of the product, I'm sure, but it makes it difficult to get people to even know we have a commercial offering, let alone what it is and does and why it might be beneficial.
I could see the same thing for Minio; even if they have a great OSS product, a great commercial offering on top of that, and great support, getting people to even be aware of it in the first place is going to be a huge challenge and getting people to pay for it is even harder.
It's sad that they went the completely wrong direction and started taking things away from the community to force people to the commercial side of things whether they're willing to pay or not.
I reckon they gave away too much, and are clumsily rowing it back.
Gitlab seemed to do a good job of navigating a community edition as an on-ramp for sales. But it's obviously a lot of work to maintain that edition, and VC must be feeling less geenerous than 10-15 years ago.
e.g. maybe if it were my project I'd have kept back the S3-compatible ACL support and put in something super-basic. Or even cluster support. Right now it feels like they're cutting off everything they can while still being able to call it "open source".
