Sport is not fair and F1 has never been fair. Honda powered cars won 6 WCCs on the spin in the 80s then immediately afterwards Renault won 6 on the spin and in the naughties Ferrari engines won 6 on the spin, just look at the WCC over the years to show some dynastic eras:

Renault had pushed hard for this engine and Horner knew it when they extended their agreement in 2012 which would cover many years into the hybrid era. In Jerez 2014 a few Renault mechanics went on record to say that RBR were not allowing them full access to the car to see what the overheating problems were. Horner and Marko have been combative at best in their relationship with Renault, so in light of this would you supply RBR with an engine if you didn't have to? I certainly wouldn't and Cyril doesn't look overly keen to do so either hence Renault returning as a fully fledged works team and Ferrari and Mercedes have made damn sure they didn't have to.

Regarding your tyre analogy- if Merc had partnered Michelin and Michelin then begged for the rules to be changed to suit them or they'd leave so the rules are changed, then Williams' new Dunlops spank everyone while the Michelins explode every other Sunday, just how much sympathy would you have for Merc and Michelin? If Merc then slagged off Michelin at every single opportunity, would you expect Dunlop to supply Merc if asked or keep their distance?
Ultimately all of the engine manufacturers and all of the teams voted in favour of these hybrids except Ferrari on most occasions who still wanted V8s. Even Monisha was in favour of the hybrids before they were introduced.
Ultimately it is motor racing, it shouldn't be a surprise that a major motor manufacturer nailed their engine. Ferrari are there or thereabouts, they came close in 2017, it really was silly things that robbed them of so many points as the fundamentals of the car were fine. I do agree with you that the teams have far too much power and I think Liberty should be prepared to call Ferrari's bluff- and anyone else's for that matter.
I'm not a fan of any team nor driver by the way.
