I had a similar experience with MS employees for an issue on a third party SQL driver using it with Azure SQL... very courteous, professional, and was included on some internal email chains to keep me informed. It did take a couple days, but the effort was very nice to say the least.

It was an Azure team member that spotted the bug and worked with some of the MS SQL guys to resolve the issue.

I can't speak for the larger organization, but will say that the Azure and .Net Core teams have been incredibly open and responsive. And with a huge amount of their devdiv stuff in Github, it doesn't surprise me they'd be one of the largest corporate contributors on Github.
