I wasn't around for them, but apparently there was at least one rather contentious hard fork. Back when random X was introduced that stopped ASIC miners from being able to mine it, and the original, I guess, was called "Monero V" or something. Obviously, most of the community did not want that because they want digital cash and believe that anybody should be able to get their hands on it. And ASIC devices would prevent that. Also, the Monero community believes that ASIC devices are extremely centralizing because only a couple of manufacturers make them. They only have one purpose and they can be easily tracked from imports and stuff. Like, if I buy an ASIC, there's only one thing I'm going to be doing with it, and that's mining crypto. But if I buy a high end gaming computer, I might be mining Monero with it, but I might also be playing Skyrim, or something like it. And they don't know which it is.
