I used to go to an event which I originally enjoyed, but after a while it became about the woman running it. Her name became almost as well known as the event itself and she'd post loads of stuff on their social media about how her project had grown etc. It all became very egotistical and cliquey.
Is there a term for when this sort of thing happens?
A more famous example I thought of was Wikileaks, where Julian Assange has become more famous than the website itself.
I looked up Cult of Personality but this seems to be used for dictators so it's not quite what I'm looking for.
