The problem with Apple's stance is that you can't use any app on your phone if Apple doesn't think the content is OK. That's very annoying for certain groups in society.
There's a gay dating app for dudes who are a bit kinky. Leather, latex, being tied up, things like that. On iOS devices, they've had to restrict the app. You can't look at the photos on anyone's dating profile because "they may contain adult content". What's the point in a dating app where you can't look at pictures?
The Google Play store has the same rules, but Android devices allow app sideloading. The dating site gives you an APK you can side load onto your phone and it does let you look at pictures and do everything else.
I get that "a lot of people won't want smut on their phones" and "protect the children" and all that, but I'm a 35 year old man and I'd like to see what "leatherdaddy42" looks like. Who are Apple to decide I can't do that on my iPhone that I paid $1,000 for?
And when a friend sends me a link to porn he thinks is hot, Telegram on iOS says "you can't view this on your device because it may contain adult content". Yeah, I know it probably does. This friend is a dirty so-and-so. I'm 35 years old and I'd like to see it please Apple.
