If it's all open source, why does it matter? My node_modules folders are a good example of why having thousands of individual open source fiefdoms is not always a good thing. I don't think the Avalonia example is a good one either. Nobody talks about why Ruby on Rails doesn't support Sintara. In other ecosystems, every project is in competition. Why should .NET be singled out. I think the argument that open source software can't compete with Microsoft is total bunk. If the alternative is competitive, it can succeed. Dapper has been around for over 10 years. Avalonia is "used by >170,000 companies, including 431 on the Fortune 500 list" according to their own website. Xamarin joining Microsoft is pretty much why we're talking about .NET 6 right now. Microsoft's first party solutions are really very good (in house or acquired). This is again why you might choose .NET over a more chaotic ecosystem.
