Why is iOS always lacking in basic YouTube viewing & downloading & ripping functionality?

While iOS can actually do primitive rudimentary YouTube video downloading,
ripping and viewing functionality, the good stuff is reserved for Android.

Why?

Why is iOS always lacking in basic functionality, such as, in the case of
this thread, iOS' YouTube viewing & downloading & ripping functionality?

To flesh out how fantastic the FOSS YouTube-without-ads truly is...

What NewPipe gives you is privacy from YouTube tracking on Windows.
All using the Windows display, mouse, keyboard, clipboard & speakers.

You can size the Windows NewPipe video display to a full screen.

There's no need to create a Google login - even to subscribe.

And, best of all, you control the entire Android phone from Windows.

Certainly you can download videos and rip music and share videos,
all without ever seeing a Google-inserted advertisement in the video.

Works over Wi-Fi & USB using FOSS tools which are always free & ad free.

Why doesn't functionality that modern & useful work on the iOS platform?
