If you bought a car that needed to go 60mph and a subsequent update to the car from the manufacturer for safety meant it could only go 30mph, there would be legal consequences.

Of course you can't predict every contingency, but some of them you pay for.

Did Intel ever specifically 100% promise a certain performance in their advertising? Do they have contracts having such promises in them with vendors?

Yes.

They showcased benchmarks and paid people to benchmark/review their product along similar lines.

etc.

I have seen Intel post benchmarks that are no longer correct. So, yes.
