The two people in that "Barnes Law" video engage in an extremely dishonest form of argument. According to them, the fact that somebody cannot name the specific evidence Jones' lawyers were ordered to produce in discovery somehow negates any views they might hold on the case, including that the
default (not summary) judgement was fair. It's a cheap rhetorical trick for use when one has no better argument: come up with some detail one's opponent doesn't have to hand and attempt to claim that because they can't immediately answer that specific question they must therefore be wrong about everything. The use of this form of argument is in itself a strong indicator of bad faith.
IANAL, but with a bit of Googling I found one of the requested items of discovery detailed in the Plaintiff's motion for expedited disovery at [1], in the letter from 2018 quoted at the end. It's a specific InfoWars video segment from 2017 that was no longer publicly available as it had been removed by Youtube and Facebook. Rather than provide this video or explain that (and why) they couldn't, the defendant's lawyers simply ignored the discovery request for more than 2 years, despite the court granting the motion for expedited discovery in october 2019. This and numerous other abuses were the reason for the default judgement [2].
This information is available if you go looking for it. A lot more is presumably available if you have access to the necessary resources: Lexis Nexis, etc. However, the fact that some particular individual doesn't know it off the top of their head obviously has absolutely no bearing on whether the default judgement was reasonable.
