I suspect it has more to do with the American culture. Every time I watch something American, be it a TV show or YouTube from a big name, things are constantly bleeped out or you notice they don't mention swear words. It's super annoying - either accept it and stop beeping, or stop swearing all the fucking time. It's also not as if you have no idea what that beep meant.
They are fooling the content filters some corporate services use to block emails though.
