Might be because there's a lot of people like me that only like that style of beer. I don't dislike other types of beer, but I'd rather drink something else than a lager, stout, porter, pilsner, etc. I've found that there aren't a lot of diehards for any other style, but IPA diehards are a dime a dozen.
Agreed, IPAs(west coast, hazy, etc) are pretty much the only beer I enjoy drinking(for taste). Occasionally, I'll take a lager on a hot day when I want something really "light".
I could drink a hazy pale or NEIPA anytime, it would be my desert island style for sure. Never liked the high IBU IPAs that were everywhere for a while because of the bitterness. (And I love all the Campari-adjacent cocktails)
I feel similarly about the store-bought THC products in Canada. They're like high ABV, hopped-up IPAs when really I just want a light, refreshing, repeatable beer with good flavour.
