Your missing at least my point.What about when the Cosworth DFV was the predominate engine in F1? Were Lotus and Tyrell not legitimate teams when they won championships? Or Williams with Honda? What about Cooper, when it won as far back as 1959 with a Climax powerplant? In fact, in that era, Rob Walker was able to win numerous races as a privateer with Stirling Moss running year old chassis. This isn’t really new. Indeed, I would suggest that to some extent and certainly with virtually unlimited budgets, the factory teams have destroyed F1.
