I go by my vet recommendations and I agree with his stance. Ever since seeing that office my animals have been doing amazing. Before I was listening to vets who told me not to use hay... someone also said just because you can eat McDonald’s every day doesn’t mean you should. Same goes with animal diets it’s best to do their natural eating. Pellets do not grow in the wild. Most pellets are made with stuff animals shouldn’t eat... they can get away with a lot on animal feed. Just like McDonald’s gets away with a lot with their food. There are nasty chemicals in it.Please realize that the way this is phrased implies that you are the only good owner and people who do not treat their rabbits as you do are tantamount to killing them young. This is not a good hot take.

Note that all of these sources, from agriculture to medical to house rabbit society, cite 8-12 years as the average domestic rabbit lifespan in good care. And the Guinness world record lifespan for a rabbit is 18 years (currently oldest living is 16). Comparing this to the world record holding cat at 38 years, you can see how these are different.
Suggesting that someone whose rabbit develops severe health issues in the end stages of their natural lifespan is providing inadequate care is neither helpful nor accurate. There are many ways of keeping rabbits and many of them do not involve hay and result in long lifespans. Many of them include hay and involve short lifespans and improper nutrition. I understand your frustration with inadequate education on animal nutrition but it's always better to be helpful and check your facts twice.
