To be clear, that's not correct we did do this to mitigate the bug.

We were facing the bug that I described (the cross stream thing) showing up when Lantern was used. It was causing disruption to our service and customers were writing in. We were trying to understand what was happening and needed to stop it. One of the things we did to stop it was disable domain fronting. As we were seeing the customer reports we didn't know if this was an OpenSSL bug, something in NGINX, something in our code, but we did know that Lantern was somehow causing it and they were doing domain fronting which wasn't the standard use of our service and so we dropped it.
