Food is food. Do what you want to do to your food because you are eating it. Other people aren't eating it so they don't get a say. If most people saw what the original pizzas were they wouldn't recognize them and some wouldn't like them, including modern Italians.
Tabasco, in my opinion, is just like eating a pizza with peppers or a bunch of pepper flakes on it, or as I sometimes do, ground cayenne pepper.
