I don't understand what the fuss about this is. I used to use TrackIR for years up until a week ago, so I used TrackIR before and after these changes. The new way is more correct by the way. When view is centered (pilot is looking straight forward) you are not looking downwards, you are looking straight ahead, and this is how new settings are set. To call this unusable is just incorrect. I have used it without issues so it is not unusable. You can say you prefer the old way because you are used to it and you want by default to be looking down a bit into the instruments, but reality is pilot to see the instruments needs to look down a bit, so again new way is more correct.
Also ED is indeed listening and they might revert the changes (this is just my guess), maybe even make 2 separate view settings for those using VR and those that don't (and use TrackIR instead).
