Oof, this won't help you, but I recall sending a very angry email to me new corporate overlord in the Xbox org for blocking me from using their web services if my user agent said Linux. This was during the "Microsoft <3 Linux" campaign, and I think I cited that and then told em Minecraft would not be able to move forward with Xbox account migration until they stopped such idiocy. Since I was the dev tasked with migrating Mojang accounts to Xbox accounts, I felt I had at least SOME credibility to my claim that it was blocking me. But honestly, modifying my user agent was easy, it just pissed me off. They did fix that the same day tho, so I guess the believed me!
