The "lied" bit is debatable because there's multiple ways of interpreting his statement. It could be "there's no liquidity issue [and we could have let GME stock trade freely without running into liquidity issues]" but also "there's no liquidity issue [anymore, because we stopped GME from being traded]". The former clearly favors WSB's narrative, so that's what everyone there believed, even though it's reading too much into the CEO's statement.
