I believe it actually says "gaps in U.S. and international enforcement of legal prohibitions on informed trading.", then later goes on to say

" But as its name suggests, the U.S. law of insider trading is a poor fit for trading patterns of the kind we document here." (page 38).

So it does seem to understand that insider trading doesn't apply to the data here. I think "informed trading" meaning prior knowledge (not insider company trading) is the relevant point here.

its good entertainment, they should have left a patreon link at the bottom
