Re: Hmmm...
And why would Telegram want to allow its users to use WhatsApp to send Telegram messages to other Telegram users, or to modify its app to send WhatsApp messages to WhatsApp users?
They can mandate this all they want for Facebook, but unless the little guys go along with it nothing will change. Any interoperability with WhatsApp or Facebook Messenger means even more data going to Meta. I don't think they've thought through this law very well.
