The likes of FMovies and movie-web offer a virtually unlimited catalogue that contains everything you could ever stream, for free. And their streaming quality is almost always at par with Netflix, if not more. There is zero rational reason why anyone would turn to those “legit” streaming platforms if they know about them.
The only thing separating is app support on smart TVs. It’s Game Over once TVs start allowing PWAs and ad-blocking browsers (do they already? I don’t know).
