I agree that a single standards protocol for chat would be good for everyone. However, I’m
extremely skeptical that governments regulating, and defining, that standard is a good idea. The first problem is that there are many different governments. Will each have their own standard, or will it be another extrajurisdictional legislation like GDPR? The second problem is that any government regulation is going to include clauses that benefit the government and law enforcement, e.g. backdoored encryption.
If, and it’s a big IF, the government could force a standard that was limited in scope to interopability, with no backdoors in encryption or increased cost of implementation, then I could maybe get behind this idea. But given the past behavior of governments regulating technologies, and feature creep of regulation, I am extremely wary of any new legislation to regulate technology standards.
