I agree that's the ideal solution in a vacuum, but I don't know this person's responsibilities regarding the projects in question, so I don't want to make assumptions about what they can or should do.
If their job isn't to handle bug reports against .NET, what are they doing writing confidently about what should happen as a response to a bug report against .NET?
I am taking no stance about their responsibilities. What I am saying is they should have made the ownership of the next steps clear. Who the owner is depends on their responsibilities, which I don't know.
