Retroactively! It'd be one thing if it was up-front rejections, but the internet is full of horror stories from developers who suddenly found that Apple had decided their product was no longer okay and that their customers didn't matter, blocking future updates. Not even necessarily taking it off the store, just ensuring it can never get bug fixes.
Well you have the extremism bias. Only people that are really mad at apple will voice their opinion. You probably won't hear from the thousands or more of developers who have no problem with publishing on Apple platforms. Since it's nothing out of the ordinary they don't go out of the way to comment how awesome it is to publish on there.
And also what I've seen with these stories that there is always a human from Apple App Store review involved, the conlusion often are a phone call with an apple rep or something like that. That's one of the things that's often not true in cases like Google - no humans to reach.
So true sometimes Apple pulls an app, unrightfully, like Amphetamine or etc. but they usually reach out back and you can talk to them.
