GC pauses are not the real reason people hate GCs even when they say otherwise. It's mostly about the cognitive overhead GC imposes on you and compromises that it forces you to take. If it's there - you are always aware of it, you cannot ignore it, you know it's unpredictable, but you know there are better predictable choices and it makes it very hard to feel good about the quality of the software you write. It's like it forces you to accept mediocrity.
