This is a crap article, to put it nicely. The article barely even talks about funding, and only mentions it in the context of the .NET Foundation, which is not all of .NET's massive open-source community. .NET has a thriving OSS scene and, frankly, NuGet packages are often of far better quality than anything you'll find on NPM. .NET receives regular releases and security patches. The article spends far, far too much time talking about .NET Framework, which is not the same as .NET (formerly .NET Core). The entire point of .NET Core was to be cross-platform; this means things that are Windows only (COM, WCF, WPF, etc.) were and are deprioritized. This surprises no one. If I didn't know any better, I'd say the whole article is a submarine marketing piece for AWS.
