For me Cameo, more than any of the celebrity zoom calls, twitter sing alongs etc... has busted the bubble of celebrity.
For better or worse, society forces celebrities to live in this superposition of untouchable and relatable. Cameo kills the untouchable part because it's putting a price on their time - which to the layperson like me feels invaluable - even if we know that there is certainly a dollar figure to it.
$30 per second [0] is unreal money for anyone - If the numbers are right Hasselhof has made $11,000 for doing 51, 30 second videos. So it's certainly a benefit from each side, obviously! At that rate he could work ~30 minutes per day during the work week (2 videos per day, a couple of tries, login and upload) take a full month off a year and still make $140k.
I think for me it comes down to the realization: "I can't believe these huge celebrities have time for this" - but it could just be an artifact of quarantine.
