When .NET (that is, what became CoreCLR runtime flavour) was open-sourced, it was done in such a way as not to cause issues for existing Mono, Xamarin and Unity code, and allow cleanly merging the first two into overarching .NET ecosystem.

Given that MSFT never sued anyone for .NET or .NET-related matters, so far their reputation is clean in that area, unlike certain Java-related company.

This is not a refutation of my statement. The episode I mentioned came years before the opening of .NET core, and the threat of a lawsuit was very much real at the time. Their track record is generally still one that does not promote trust.
