There is nothing wrong with sex parties, nor drug use. But a lot of these VC-adjacent parties have reports of strong power imbalance- “young female founder seeking funds, wealthy VC seeking partygoers”. That is the issue with them.

(Like those described in the removed link)

Altman is a married gay man, so his involvement in them seem… less likely.

That's just prostitution with extra steps, no?

It's a secret that there are parties where people get drunk, take drugs and have sex?

I'm pretty sure that's not a secret. It's just the definition of a party if you're a young adult.

It's a bit creepy when the ratio is 2 to 1 or more and/or a significant age difference of the male to female attendees...

OP included a link (subsequently removed) to a description of these supposed "parties" that describe them more like the ritualized sex mansion scene in Eyes Wide Shut rather than a normal young-adult "let's get wasted" party.
