I don’t know … (about NTTS Video)
He criticized stuff that is just normal, like the validation of encryption via codes (WhatsApp has the same system, just with qr-codes). Which can not be technically better implemented (besides some “design” things like qr-codes or overall better usability by design). He complains that E2EE is for the most people useless and at the last point he mentioned (not his own “opinion” but an uncommented quote) that discord can’t implement E2EE for chats because of child safety and that this would destroy discord user reports.
Furthermore, he is by far the biggest discord YouTuber and has with this video also an influence on the people and how they stand to the encryption of Discord — do they reject the implementation or do they want E2EE.
