There are other App Farms we know of…. One example is Brighthouse Labs with 4568 Apps, all virtually worthless.
I have a hard time wrapping my head around that number. Nearly five thousand “apps”. Near as I can tell, it’s a solid 2% of the whole App Store. With an (optimistic) 5-day-per-app approval time, it would take Apple 86 years to approve them serially.
