You’re likely going to have to wait until trial or for a party to leak something to YouTube (and even then, I’d take with a grain of salt, bc can be out of context or intentionally misleading)
Discovery materials aren’t flashy and aren’t typically filed with the court (and therefore aren’t public.) So unless a court filing attaches something like Answers to Interrogatories or deposition excerpts to a motion, there’s not a lot of opportunity to examine “actual evidence”. There just aren’t daily/weekly public developments in a case like this.
Discovery is a slow and boring process dealing with stuff like Subpoenas for documents, compromises over electronic discovery search terms, written objections, corporate designee testimony, deficiency letters, meet and confer meetings, motions to compel - and depositions themselves (oooo testimony under oath) can be 7 hours long or sometimes longer. Sometimes the most legally significant part of a depo can just be acknowledging or admitting that a document is authentic.
All that to say, you can’t judge the strength of either side’s case yet - especially because I’m not sure they've started the discovery phase in the California or NY cases. And you’re likely going to have to wait a long time before anything significant happens in public
