So, it turns out Bret did discover Odysee, because Youtube's "two strikes" against his channel made it impossible for him to livestream for a while. Good on him! He even says he likes Odysee as a platform better, because he thinks it has more advanced features. Not sure what that means. Neither he nor Heather strike me as especially technical. And in terms of the polish of the UI, Odysee as of now is far inferior to Youtube.
Also, as he and Heather were quick to share, a new meta-analysis of ivermectin studies has just been published in the peer-reviewed American Journal of Therapeutics. I don't know if this changes anything, but it sure will be hilarious to watch if the official stance on it changes and the Overton window slides again.
