Really, people have a specific "hate heuristic" and whatever triggers that they will hate.

It can't really be reasoned with because it's a subconscious reflex.

Heuristics overwrite reasoning for most people because they don't consume much resources in the brain, the cheaper path is selected by default.

I agree with you, but I think it's also easy to see where people like the person you're responding to are coming from. Corporations have become pretty nasty in modern times. It's no longer really about offering the best product for the best price, but instead coercing and exploiting people so much as possible to squeeze every single penny out of them, offering as little as possible in return, and then somehow turning everything into rent.

Age is often a factor here. If you're older then you've known a different world of capitalism than what's being put on display in contemporary times. By contrast for younger people, this sketchiness is all they've ever known.
