I would say that .NET is the best example that Microsoft has not changed: https://isdotnetopen.com/

The website doesn't even explain what they mean by open.
Nor they explain why they think .NET is not open source.
Further, the twitter posts themselves are still relevant I believe. If someone took over my repo, I'd remember it 3 years later.
So far, there was little demand to write another debugger integration (because, really, the debugger core is implemented in the runtime itself - what vsdbg, NetCoreDbg and Rider all primarily do is consume the runtime API).
I'm baffled by insistent behavior like this. I think it is just alienating people and even if they move ecosystems, the negative impression will stay.
If you engage in bad faith behavior in a technical discussion, can you be expected to conduct yourself acceptably in a professional setting? Unlikely.
This is a discussion about HTTP/3 support of all things. Why does it happen only when someone leaves a briefly positive note on C#? I don't know any other language (besides PHP, to an extent) that gets the same amount of hate.
The link itself is also quite outdated and mainly consists of posts from Miguel de Icaza who's promoting Swift, arguably less OSS language. Take from that what you will.
Fanboys are a bit in denial about this.
I should also add that the general public only saw the tip of the iceberg in this entire episode. Miguel spent a lot of time and effort internally trying to right the .NET ship, gradually escalating through management until he finally gave up.
Instead, the complaints you will read here are about what the authors think .NET’s problems are without ever verifying if any of that is true in hopes of making swipes for god knows what reason, because posting something accurate requires knowledge on the subject and the results of a cursory search usually do not support cheap arguments.
(and I see this as an embarrassment because you can learn a lot from doing research instead of repeating the same tired phrases you heard elsewhere)
Call it TypeScript++ or just `dot`; rebrand it Microsoft! Look at this thread full of misunderstandings and confusion around modern .NET!
Speaking for myself, I happen to like .NET from the technical perspective. While both the language and the stdlib have a lot of cruft from days of yore, it can mostly be ignored, and that aside it's a fast runtime with a decently expressive type system giving one considerable flexibility to pick the right tool to model different domains. It also has great tooling around it. But this all is separate from the question of how open .NET really is, and its long-term prospects in that department.
