The Danish Dude has a video, in his website, an interview of Marc Cohodes about a case against Goldman Sachs and separately talks about Citadel in connection to the Gamestop situation of Jan 2021. Exactly as you say. Worth watching.

Very interesting video indeed.
Marc Cohoes does not beat around the bush.
His fund lost half its value, from $2 Billion to $1 Billion when Short Selling rules changed. Wow.
Trading rules are still staked against "Joe 6-pack" ... the common investor.
He considers Citadel a villain, which poses huge risk to the US economy. Another "too big to fail" problem.
He certainly has a dislike for Goldman.
