You mean the apps that Apple was fine hosting on their platform and taking their 30% cut from up until Apple decided to create a first party app that can control your phone and spy on everything you do?
That doesn't distract from the fact that analogous third party apps in this category was wholeheartedly permitted on the App Store until Apple decided they wanted their own app in this space.
Well, they should have cracked down on that spyware earlier, and their failing to do so until they had a competing app to push both casts their motivation behind banning those apps as suspicious, and calls into question the supposed "quality" of the review process. At worst, they did it to Sherlock competitors. At best, they were negligent, their review process is overrated and does not do enough to protect consumers against spyware. It is on them to justify their poor timing.
Apple should have cracked down earlier, simpler as that. The fact they didn't makes them look like hypocrites. I'm aware that it's impossible to go back to earlier and crack down then to not look like hypocrites. So it's important that going forward they are less capricious about enforcing App Store guidelines and don't make themselves look bad.
