This is still the best evidence I've seen that we're right. Right from the SEC itself, esp pages 25-26 regarding short selling, but there's some other nuggets in there as well.

GME is the only stock that staff observed as having short interest of more than shares outstanding in January 2021.

Given the high levels of short interest, together with the price movements in GameStop, a natural question is the degree to which these price movements arose from a “short squeeze.”

Figure 6 shows that the run-up in GME stock price coincided with buying by those with short positions. However, it also shows that such buying was a small fraction of overall buy volume, and that GME share prices continued to be high after the direct effects of covering short positions would have waned.

...it was the positive sentiment, not the buying-to-cover, that sustained the weeks-long price appreciation of GameStop stock.

Boom. Shorts never closed. Squeeze hasn't squoze.

The short interest reported to the public is a manipulated figure, and the fact that more shares were publicly acknowledged as being shorted than even existed as shares outstanding confirms that these hedge fuckers engaged in naked shorting.
