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.
