Is There a Right and Wrong When It Comes to English?

I've heard from so many creators were not English teachers, who are non native speakers, how much crap they get on their pronunciation. Despite the fact that they're sharing their knowledge and they're doing it in the second language. It's really crazy how a native speaker can really say whatever they want. And people will just assume that it's true. I'm happy when our students or anyone in our audience says that they feel so much better about their English. After doing our courses, like new sound, or watching videos that really makes my heart happy to see those messages.
