It's worth it to be able to download actual Firefox / Chrome / PPSSPP / PornHub / etc on iOS since Apple bans them for no reason
Can I buy porn from most mainstream retailers?
But by “porn” do you mean Playboy level nudity or more hard core?
Well, we don't know. But porn has historically been at the forefront of digital technology, so maybe some investment in sectors like AR and VR is being held back by the fact that Apple would never allow porn-related apps.
It's also not trivial to install Android apps outside the Play Store, for non-geeks.
