That's a pretty one-sided view though: I take it you're looking exclusively at technical innovations (and even there I dispute your assertion about Ferrari). HOWEVER, Ferrari brought the fame and the famous and fans to F1 and therefore $$$, which no doubt helped McLaren (and F1 as a whole) way more than what all the other teams combined have done for F1. In fact, that contribution and elevation of F1 by Ferrari has provided the basis (financial and otherwise) and opportunity for the other teams to come up with their contributions.
To be honest, DD, the only ground-breaking piece of innovation that I can think Ferrari came up with was the semi-automatic gearbox, but even then it was designed by an ex-McLaren engineer and was perfected by another team. Don't quote me on this, but it was not until the McLaren MP4-9 came along (so 1994) that the gearbox became fully semi-automatic, for McLaren devised a way of removing the clutch pedal and having the clutch controlled via a paddle on the back of the steering wheel. As I've said a couple of times before, kudos to Ferrari for having the distinction of being the oldest team in Formula One, although it counts for something, it's not enough to make them the greatest team ever. For the most part, Lotus are the reason why Formula One cars look as they do today. They are the greatest Formula One team ever. McLaren and a couple of others have to fight it out for second place.
I'm also not sure that Ferrari contributed all that much money to Formula One. In the early days of motorsport, Ferrari were seen as tag-ons to Alfa Romeo. Also, throughout their Formula One history, Ferrari have had very lengthy barren patches. It was Lotus who brought sponsors into Formula One, being the first to ditch national colours in favour of a sponsor's livery. Other teams then copied. In the 1980s and '90s, Ferrari's support was not all that extensive outside of Italy. It was McLaren and Williams keeping Formula One afloat. It's only really since the late '90s that Ferrari have begun to contribute to Formula One for the first time God-knows-when. The rise of manufacturers also means that Ferrari's contribution is not key to Formula One. If Ferrari were to leave Formula One, it would be a travesty, but no one team is bigger than the sport. Plenty of legendary teams and drivers have come and gone and Formula One is stronger than ever.
