I don't know what the frequency of his uploads is, or how current the content is. I think the former is more important than the latter. If you are paying him a monthly fee and you are getting less and less in return, the value for your dollar goes down. Either you look for a lower tier of support to switch to, or you cancel for a month or two to see if he gets back on track. If the amount of content is going down and he is also talking about reducing it to a trickle, or stopping altogether... that is the start of a death spiral.
And that is just talking content and value-for-your-dollar. How many of his remaining supporters are wondering what he is referring to when he mentions misinformation campaigns and internet bullies targeting him? How many of them will seek out information that he is not giving them, and learn things about him that will make them question their support? More than 500 of them so far, it seems to me. And so the number will keep dwindling until the only ones left are that core of hardcore supporters who cannot let him go. But I don't think they will be enough to prevent the ship from going under.
