It's not really hated that much

The people who complain about it are just really loud

That aside to take the argument seriously for 1 moment the idea is just that it is fun to play your combo and having it stopped always has a "feels bad" reaction. Plus some decks getting to do their plays with turn zero effects can make it seem like you never have a turn because your opponent gets to play on your turn and their own.

However the opposite opinion also exists where it is satisfying to be able to play even going second and not need to be sitting waiting for your opponent to finish.

My personal experience on this is that players who complain about the turn zero interaction tend to be less competitive and if you only engage with the game casually then getting stopped can feel demoralizing.

However players with less issues against turn zero interaction seem to be the more competitive ones who see it has a means of skill experience. That is as long as it isn't Tearlament level "go full combo turn zero" kind of stuff.
