You're having the same conversation with me on multiple threads and it's me who is thick? It seems like you're personally insulted when someone does not choose the tech stack that you identify with. It's a language, not a religion, you're going to be ok. I have my reasons not to like it and you do not have to approve. Get over yourself.
Feel free to do you, I have told you this already. Seeing you're unable to drop the conversation, when did Microsoft ever sue someone for using C#? I trust Microsoft far more than Oracle (reasons detailed in another comment). However, I do not run Microsoft software at my company at this time, other things work better for what I need.
Google got sued for using the language. They won, but I can't afford that fight. They might lose but I refuse to believe that Oracle won't change their mind in the future and decide that anyone who breathes the word Java owes them money. Oracle can't be trusted.
C# is not my first choice but I did tolerate it the last time I worked a corporate job. MS seems committed to .NET core being open source and have never tried to rug pull C# or the .NET framework itself.
Also, I believe Microsoft's incentives are different, and in a way that benefits me. For instance, they sell more Windows Server licenses because it's easier for legacy shops to administrate (even though it can be done with nginx now). They also get more native software released for Windows, sell more Visual Studio Pro licenses and are able to steer people toward Azure DevOps and other Azure based cloud services.
Oracle has some similar products but their revenue streams are miniscule in comparison. They also have historically been a very lawsuit-based company, as an aggressor not a defendant.
It's their business model.
