Sorry, I don't follow your reasoning. Why would a company not making money be a relevant problem for the advocates of FOSS? FOSS is about freedom. It never had an opinion about money. Money has always been irrelevant. Some people may not like it, and they are free to not use non-free licenses. And FOSS advocates will warn users about that (as they did in the past). FOSS doesn't have an obligation to offer a solution to every problem in the software industry.
I don't think that is relevant from author's (and OSI's) point of view.
Here is my understanding of author's position: Stay away from companies like Redis and ElasticSearch. They are building software with a proprietary mindset (the fact that they have tight control over product strategy and development demonstrates this) only to realize that they are being devoured by bigger fish. It's a business model problem, not an open source problem.
I think you are highlighting an important point that are missed by other commenters emphasizing the developer. I prefer GPL over MIT license. But this is a possible fallback if Redis decides to change its licensing (like several others did).
I think these kind of products have strategic significance for MS for their Azure offering. They are probably preparing to offer this there (in addition to and as an alternative to Redis). So, it makes sense for Microsoft to release this with an OSS license (otherwise no one will adopt it).
What checkout actually does. Here is a past comment with links to the courses (they are pay-walled, unfortunately)
I don't think I read that one. I created a separate link-post for that one. Thanks.
Mine happened when I watched Paolo Perrota's Git courses on Pluralsight. That's when it clicked for me.
I mainly develop in C#, and I agree that having to write so much boiler plate for type safety is really boring. C# is not perfect either (it doesn't have discriminated unions, etc.) but at least it gives type safety out of the box.
However, in general, I think enums are widely misused. I see a lot of cases where they should have been classes with a factory, but ended up being enums with a lot of static functions and switch statements.
Who is this particular developer
As far as I understand from the discussions about the topic, Maxim Dounin was one of the few core developers of nginx. Looks like Wikipedia has already been updated.
I don't follow it very closely, but as far as I know, they are the only one implementing the open protocol they designed (which doesn't interoperate with ActivityPub). However, there seems to be some efforts for creating a bridge: https://www.docs.bsky.app/blog/feature-bridgyfed
As you said, there are some recognizable faces and that may impact the adoption. But not being compatible with ActivityPub is a real bummer.
That's an unnecessarily strong reaction. Money clearly matters for some things. But that's not all that matters. There are many people releasing FOSS without any financial expectations. Clearly, money doesn't matter to those people on that context. Trying to argue that "money should matter also for those people on that context" doesn't make too much sense to me. Nobody is forcing anybody to release FOSS.
