Does pineapple go on pizza

It's not bad at all. It goes very well with some hot stuff like jalapeno etc. Just the right balance of sweetness and spicyness - delicious. I mean there is a reason sweet chilli sauce is so popular.
Even my granny put it on pizza and her best friend, a true italian nona, approved it.
And seriously, people put much weirder stuff on pizza and sell it. Only to Mention fries or some really nasty goat cheese.
