You know, it is a good thing, that Meta is creating an ActivityPub/Fediverse compatible social media system with Threads because it instantly legitimizes the protocol. That said, it could be argued Microsoft did the same for HTML/HTTP when it built a web browser in the 1990s, but I still managed to avoid using Internet Explorer except when absolutely necessary over most of the past 30 years. The important thing is the underlying open system and freedom to choose.
