I don't see how that incriminates anyone myself. It was mentioned during the race coverage on SpeedTV that other teams on the grid might still currently have the same system as RB that require no tools to adjust ride height. I really don't see the issue unless the FIA has evidence that someone actually changed the ride height on a car, and really can't see why they have to change it. If the FIA wants to make sure the knob isn't moved, they can plant a sticker type seal on it like they do so many other things.
