Based on what we know about Flavio Briatore now?

Can there be any doubt at all that all of the cheating allegations levelled at the Benetton team and Schumacher in the 90s were actually well founded and probably true? Isn't actually probably more true that we are only privvy to the cheating they didn't get away with and that in fact Schumacher's early career success was as much down to illegal electronic aids, car lightening moves, intentional collisions with competitors and team orders as it was his developing talent?
