So it looks like the are taking “free” 3D models from FSX (which they probably don’t have permission to use), probably some liveries that they didn’t make, merging it with the A320 cockpit (possibly with stuff stolen from FlyByWire?) and then selling it?
Personally I think that Microsoft should take a very hard stance against things like this. This group is using the trademarked MSFS logo on their website. Someone from Microsoft legal should send them a cease and desist.
