louis rossman talks about this in two of his recent videos on twitter and reddit. obviously he tackles it using layman's terms, but there's still a lot of valuable insights and it's super palatable.
essentially it boils down to what @OsrsNeedsF2P@lemmy.ml says here:
"The valuation of a lot of these sites was grossly inflated by the market, so when the largest shareholders saw their billions halve and know what the future holds, they start doing things to temporarily boost their profit margins and sell off the company."
