Right, as a customer you always prefer that it happen out of sight, but I guess these are the very tradeoffs of choosing open source software, you can't get the best of both worlds.

That said, maybe a slight change like, "I'll open a ticket with the other team" instead of "you should open a ticket with the other team" makes all the difference. But like I said in another comment, if you open a ticket on github, you aren't paying for that support, you should aim to have a commercial relationship with Microsoft and then raise the issue through that commercial channel.

Otherwise you have no recourse to complain, you are getting everything as-is.
