Yes, I agree it was many factors. This video seemed to be the breaking point, but it was certainly a long time coming. I recall several videos over the past 2 or so years where he drew attention to the invective he receives. I don’t really participate beyond watching the videos, so perhaps there are others who are more informed about the factors behind his decision.

Regardless, I wish him all the best and hope he’ll find a way to showcase his talent or at least find fulfillment elsewhere.
