Actually you're right. I think that's a fair point. It probably needs to be analyzed on a case-by-case basis.
In that vein of thought, maybe OP had a point. Snapchat/Instagram seems to feed our narcissistic egos more than anything, so maybe it's not as morally inert as I had thought.
PS: Despite being recorded "with a potato", to borrow the first comment, very relevant to basically all social media and moral good. And Bo Burnham is an amazing watch generally anyways, PSA. All of his specials are gold.
What if it teaches users the habit of selling crack cocaine? (stupid example, but you get the point)
