If they're hard to avoid, it's because lots of people are voluntarily choosing them because (in their estimation) they provide the best value for cost.
I personally find it rather annoying that the mumbly trap influence has infiltrated a lot of popular rap, and if I'm going to hang out with other hip hop fans, I end up hearing some stuff I don't personally love. But it's popular because a lot of people like it. It's not impossible to avoid -- there's just a cost to avoiding it because of its popularity.
