Simple: messaging systems / event-driven systems aren't the "fad of the day" anymore, so you don't have a gazillion vendors pumping out blog posts and Youtube videos to hawk their wares, or a million companies writing about them to look "hip" and "cool" to help recruit developers, or endless legions of consulting companies writing about them in order to attract customers, etc.
Basically every "cool, shiny, new" tech goes through this process. Arguably it's all related to the Garnter Hype Cycle[1], although I do think the process I'm describing exists somewhat independently of the GHC.
