This has been a running problem throughout the case, and one of the reasons the judge entered a default judgment against Jones on defamation liability.
Daria (the witness you discuss above) was one of Free Speech Systems’ corporate representatives. That means she was designated as a witness on behalf of the company itself and was to testify as to what the company knows. Practically speaking, that means she can’t just rely on her own personal recollection but has to study up and learn what the company collectively knows about certain relevant topics. In other words, she has to study documents the company has, talk to people at the company who know things, watch videos the company published, etc. She didn’t do that. Neither did any of the previous corporate reps (including at least one other, Rob Dew). Basically FSS didn’t do its homework and showed up to its depo completely unprepared, the judge ordered FSS to go back and study and do it over again, it again didn’t prepare, yadda yadda… The judge finally had enough of that shit (and other discovery shenanigans) and ruled against those idiots by default.
