Elon Musk has hinted for quite some time that these features, along with Fleets, Vine, and Periscope, will return in some capacity.
Fleets, Vine, And Periscope
The most crucial information is that Vine and Fleets were once popular but failed to make money because monetizing short-form videos is hard. This sparked a backlash, with celebrities such as the Paul brothers abandoning the platform in favor of YouTube and Instagram.
To encourage content creators to put more effort into tweets, Elon is exploring new methods to make money from the program. Though Elon’s emphasis on creators and a broader toolset may result in the reintroduction of these capabilities as Twitter Blue exclusive or subscriber-only tools, Twitter has not witnessed an uptick in new people joining the conversation with Fleets.
