There is no way that New York style pizza can be compared to Focaccia. They have almost nothing in common. Now that Chicago thing, maybe. But as far as I'm concerned, that's not pizza.
No one said this was NY style. The original comment was lamenting that Pizza Hut pan pizza doesn't taste as good as it did in the 80s and 90s. I pointed out recipes that directly mimic that classic pan pizza style. Pizza Hut is not and has never claimed to be New York style pizza. It's an entirely different style that's neither New York nor Chicago style. It's closest to Detroit style pizza.
