It's part of the due diligence process for users to decide if they can trust a project.

I use a few simple heuristics:

- Evaluate who contributes regularly to a project. The more diverse this group is, the better. If it's a handful of individuals from 1 company, see other points. This doesn't have to be a show stopper. If it's a bit niche and only a handful of people contribute, you might want to think about what happens when these people stop doing that (like is happening here).

- Look at required contributor agreements and license. A serious red flag here is if a single company can effectively decide to change the license at any point they want to. Major projects like Terraform, Redis, Elasticsearch (repeatedly), etc. have exercised that option. It can be very disruptive when that happens.

- Evaluate the license allows you do what you need to do. Licenses like the AGPLv3 (which min.io used here) can be problematic on that front and comes with restrictions that corporate legal departments generally don't like. In the end choosing to use software is a business decision you take. Just make sure you understand what you are getting into and that this is OK with your company and compatible with business goals.

- Permissive licenses (MIT, BSD, Apache, etc.) are popular with larger companies and widely used on Github. They facilitate a neutral ground for competitors to collaborate. One aspect you should be aware off is that the very feature that makes them popular also means that contributors can take the software and create modifications under a different license. They generally can't re-license existing software or retroactively. But companies like Elasticsearch have switched from Apache 2.0 to closed source, and recently to AGPLv3. Opensearch remains Apache 2.0 and has a thriving community at this point.

- Look at the wider community behind a project. Who runs it; how professional are they (e.g. a foundation), etc. How likely would it be to survive something happening to the main company behind a thing? Companies tend to be less resilient than the open source projects they create over time. They fail, are subject to mergers and acquisitions, can end up in the hands of hedge funds, or big consulting companies like IBM. Many decades old OSS projects have survived multiple such events. Which makes them very safe bets.

None of these points have to be decisive. If you really like a company, you might be willing to overlook their less than ideal licensing or other potential red flags. And some things are not that critical if you have to replace them. This is about assessing risk and balancing the tradeoff of value against that.

Forks are always an option when bad things happen to projects. But that only works if there's a strong community capable of supporting such a fork and a license that makes that practical. The devil is in the details. When Redis announced their license change, the creation of Valkey was a foregone conclusion. There was just no way that wasn't going to happen. I think it only took a few months for the community to get organized around that. That's a good example of a good community.
