ELI5: Why is card counting considered cheating by casinos?

Poker players are praised for their skill yet someone who uses logic and maths to gain an advantage in a random game gets vilified, and from the little I've read on card counting it's not exactly easy to do anyway.

Poker works fundamentally differently from other casino games.  In poker, you're playing against the other players, not the house.  The house takes a portion of your winnings.

In Blackjack, you're playing against the house.  Counting cards is a foolproof way to defeat them.  Obviously this hurts their profits, so they don't allow it.
