Why is pineapple on pizza so controversial?

Pineapple is frowned upon by serious pizza makers/eaters for two reasons:

1.It's an extremely wet fruit and too much moisture in pizza toppings will ruin the crust (saturate it and make it soggy and flaccid)

2.It's over the top sweetness does not pair well with traditional skim milk mozzarella or buffalo mozzarella. Both of those cheeses have about the same salt content as other cheeses but have a much more subtle flavor than say, cheddar.

3.Pineapple is difficult to grow and harvest (one plant, two years) and therefore expensiv* iteme putting it beyond the means of common people for regular consumption. Footnote : During the Georgian era, ship expeditions brought back this exotic fruit and its plants to England and they were highly prized because they were so rare. Serving one was extremely special and this kind act became embodied in Georgian architecture. Today when you see a pineapple carving above a door or on a newel post, it's a sign of gracious welcome.
