Have you ever worked on a large org with a main product that kept getting updated under the hoods to support more and more "invisible" features that ultimately drive how the product works?
Because if you did you should know that updates are constantly happening...
Twitter's longest standing and most valuable users access it solely via 3rd party smartphone apps, which use an API that's not been updated for many years and have zero new features from twitter in that time.
The service is identical to 2009 or something as far as I'm concerned, and still appears broken as far as video embeds go to this day. It's one of the heaviest and slowest loading sites I can think of.
