In this specific case Apple and Samsung have been proven dishonest and manipulative, and they have a far stronger legal/financial incentive to lie than separate groups of prosecutors in the US and many separate EU member states. I also find a conspiracy internal to Apple/Samsung much more plausible than a conspiracy across attorneys general from 34 US states.
Only trusting viewpoints that agree with your personal biases isn't enlightened, either.

is an unvarnished falsehood. The throttling wasn't across the board, it was triggered in specific circumstances related to the state of the battery. There was never any evidence that this was a scheme to defraud customers.
b) At any rate, “Apple deceitfully handicapped older products to cover up a more serious (but fixable) flaw, knowingly pushing customers into unnecessary upgrades” is really not any better than “Apple deceitfully handicapped older devices to push consumers into unnecessary upgrades.”
