Those days have long passed and most of the money is made on the b2b/industrial side. But these days raspberry pis only have a mode in software compatibility and LTS and those are slowly dwindling away. I'd be hard pressed to buy a raspberry pi of any kind these days when RK35XX Devices are available and beat pis at almost every task.
I really hope the pi foundation gets their head out of their behinds and stars competing again.
