If you're talking about Vket, vrcon and shaderfes and others like that they do stay up. 
Only corpo shit goes down like Sanrio and the vket sponsor worlds like festi-core and tokyo.
Every vket booth since 1.0 is up a few weeks after the event closes, some of vrg has booths there, I thought vrg was more savvy than this.
It's pretty simple really, they need time to remove the web launcher script.
