He’s decided to save himself some money by firing his remaining employee after sacking his wife a few months ago. It will save him money but it also means he’ll have to do the menial tasks of running his YouTube channel himself. That will be tough, but he might try to rope people into doing it for free. In fact maybe he’s already got that lined up.
Basically he plans to stop the “life saving” JW rebuttals and will make general videos and interviews that he finds less tedious instead, leeching further off the MythVision channel. He still expects his patrons to send him their money, if at a reduced level, in other words to spin this out for as long as he can. A major hurdle that his ego prevents him from seeing is that outside of Watchtower he doesn’t have anything interesting to say.
There is no need or reason to close his media company other than to hide how much money he has from others and probably from his ex-wife.
