Yes, but it does use Edge Protocol. That's why some HN users are upset. I don't think it's an overreaction, and you seem to agree that it's wrong. Responding to your edit: If Microsoft creates a new type of page that works well in Edge but not other browsers, they can make a new protocol for it and allow other browser to support the protocol if they want to. In fact that's exactly what happened here: Microsoft added a new protocol, Firefox said "we support this new protocol with full performance and functionality, so we should be able to open it".
