Gannon's description text associated with that video reads, "I will upload a video every Friday." That was posted April 29, 2019.
It never happened. No more videos. I've wondered why Gannon posted only one video.
At the tail-end of the one video we hear a whisper voice say something that, IMO, sounds like they're warning of someone's coming and then they stop recording. I can not determine exactly what is said (sounds like, "Stop recording") but clearly they don't want to be caught recording and/or playing the video game or whatever.
Whatever happened at that point may have resulted in Gannon not (permitted to?) posting of any more videos.
It was innocent fun. Who would squelch that, and why?
