Query for clarification:
Are you saying that an engine manufacturer should effectively be forced to sell engines to RBR?
While the answer ought to be obvious, it's a hard one. "Yes" for the sake of the series. "No" for those protecting their own interests to the potential detriment of a sport they need to thrive now as much as ever.
As much as some hate them (undeservedly in my opinion), Red Bull need a strong supplier as much as F1 needs Red Bull. If they don't get it, they'll leave, taking one of the best teams, the most entertaining team and four of the best and most promising drivers with them (as well as a
huge driver development programme). It will mean a metronomic loss of talent from motorsport and the end of a career for probably dozens of up and coming drivers and engineers. Imagine you're on the end of that - we've got one member here who you know who it would affect - it's livelihoods too remember, and hundreds of them. Even Deuse couldn't argue there's any good in it.
On the flipside why would either Ferrari or Mercedes supply one of their most dangerous rivals with equal equipment? Neither need the money, no matter how much Red Bull are willing to throw at them, and both have teams capable (or very nearly capable) of challenging for the title. Their only concern is how much F1 would suffer the loss of Red Bull should they carry out their threat to leave. If we only lose Red Bull and Toro Rosso and gain Haas, F1 would be worse off for it (losing a works team, a development team and gaining a donkey), but would it continue to line purses in the long run, as that's the only reason Mercedes, Ferrari, Renault and Honda are in it?
It's still a game of poker. I don't think Red Bull want to leave, but equally I think they will if there's no hope of them winning in 2017, and if 2016 is merely a year of negotiating then it may well be just a season of prolonging the tedious sniping. While Red Bull appear to be negotiating with Renault, Bernie appears to be negotiating with Mercedes, but there's an increasingly good chance we'll be short of bulls in 2016.
I think it all goes back to when Red Bull dumped their Ferrari contract on Toro Rosso to take Renault engines for themselves. Ferrari don't forget quickly and it appears to have come back to bite them.
It's sad that F1 has become such a manufacturer-based sport, but they're the only ones who can produce the goods at such extravagant levels. Privateers will
never win again and we're at the mercy of four (of which only two are any good currently) from here on in. Frankly if we lose one of Mercedes of Ferrari F1 will die painfully and quickly.
