It's an easy fork maybe, but where's the incentive to stand up a peer or replacement? They're made a paradox for themselves, in attempting to create adfree social media that moderates itself the userbase now expects the service to be free and ad free and heavily moderated by volunteer labor. This will work for a while spending millions in VC cash but I don't see the sustainability.
I've considered standing up a PDS a few times, and I think if I was going to design a financial incentive I'd wrap up a static blog host and personal cloud storage so I could charge a market rate fee (5 bucks a month for 100GB storage, whatever Dropbox is charging) and bluesky publishing and following just tacked on as a value add.
the real money would be in extending the protocol to support distributed marketplaces, so hosts could each have their own rules - disrupt Etsy, eBay, Facebook marketplace, but at some point you're getting into Silk Road 3.0 territory
