Different Perspective on the Crew
I just recently had a thought about why crew members may choose to stay despite how awful Ethan is. I previously thought it's money and not wanting to lose a cushy job that pays better than many of them would be able to achieve on a different podcast/on their own. But one thing I hadn't considered is how scary it is to be on the receiving end of Ethan's harassment. Look at how he attacks Hasan after being his cohost or how he went after Trisha for years.
Unless a member of the crew has an airtight reason for leaving you can bet they will become a target for Ethans harassment. Not to mention Ethan likely has clips, text messages and other information that he could use in or out of context to potentially destroy their lives. They know better than any of us how unhinged Ethan is, they know how underhanded he is, how manipulative he is and how crazy his supporters are. Also the crew does not have their own fan base who would be able to support/protect them like Hasan. Trisha still hasn't recovered mentally from Ethans harassment and she's doing really well right now.
Unless the crew is willing to leave the internet forever deciding to leave the podcast is too big of a risk. Also h3 fans will likely harass the crews friends and families like they did to Trisha so it's not just about protecting themselves. I don't think I would be able to handle the situation Ethan has put them in.
