I never downvoted you but it's clear you don't know what you're talking about. X has definitely not shipped way more new features in the past year than the rest of existence.

I don't even know how you would quantify that but features are only possible when you have a good architecture (incl. infrastructure and well-thought out interfaces) already in place. That kind of stuff takes years and was done by the team before Musk even took over.

I also feel you're completely discounting the regressions. Twitter has suffered search engine discoverability; the API has completely broken in their attempt to monopolize it; and the entire accessibility team was axed leading to a very broken user experience for those relying on screen readers. Maybe those features just don't matter to you but in an attempt to quantify "number of features shipped" they should definitely be accounted for somehow
