I (partly) agree with you on that. As an user, I want:

1 - speed and quality - 1080p, no buffer

2 - Good interface - netflix has great interface, Prime video is ok-ish, Crunchyroll is so damn hard to navigate

3 - just works, everywhere - Netflix has an app for most devices, works on any browser, and streams to chromecast and smart tvs. Prime doesn't cast to chromecast, doesn't work between android and smart tv app (I can't control TV on my phone). Crunchyroll... well... nope. Pirate websites have a better player than crunchyroll...

Guess which service I don't pay for?
