> This is intentional on Google’s part. It’s anticompetitive behavior, to make YouTube service’s app shitty on Google’s competitor’s ecosystem

This would be true if the Android or Android TV would have been better. It is just profit maximization combined with crappy UX/UI. Google wants your personal data and will make UI changes to get it. (double record/send button in messages, UI elements very close to others so that they can be pressed accidentally, although there is plenty of space between other UI elements)
