For some additional context about The Quartering's motivations:

• Hilary Crowder tweeted recently that Jeremy Hambly has been secretly divorced for years and hiding it. No receipts & the claim appears dubious. The Quartering made Twitter threats about suing for defamation.
• The Quartering publicly acknowledged a few months back after critics were going to leak it anyway that his entire enterprise was close to bankruptcy because he'd accumulated 300k in unsecured personal debt to buy equipment & other expenses related to his coffee business Coffee Brand Coffee
• He took another financial hit recently when his Rumble streaming deal expired and he had to renegotiate with much less favorable terms. It seems that Rumble stopped paying him for livestreaming entirely and now he only gets promoted on their frontpage in their daily lineup and a promo code cut for Rumble Premium subs. He's reportedly laid off all his behind-the-scenes channel staff but has convinced them to keep working as volunteers.
• His YT channel viewership for his infamous 10 minute culture war article-reading videos has plummeted, down by half YoY
• Despite the financial troubles, Hambly is a manchild consumer. He regularly posts new luxury purchases online for updoots - floor-to-ceiling aquariums, RC cars, expensive watches, etc.

TL; DR - Hambly's channel is in decline and his financial situation seems overextended.

He both has a personal beef with Hilary Crowder & is desperate for any social media attention to bring eyeballs back to him.
