The British company hasn't abandoned anything. The Raspberry Pi 1 still has full, modern, feature-parity support in Raspberry Pi OS,
eleven years after launch.
But fine-- in my trash bin you'll find a Cubietruck, an Asus Tinkerboard, a MangoPi MQ-Pro, and several other Chinese SoC compute sticks. Fool me once, shame on you; fool me 5 times, shame on me. All were basically given up on by the original manufacturer, and some had some degree of support through Armbian (albeit with numerous features lost due to being walled off behind some inscrutable binary blob).
The current alternative darling of the SBC enthusiast world, the Rockchip RK3588[S], does not have mainline kernel support and depends on a faux-5.x-series frankenkernel provided by Rockchip. Mainline support has been coming Real Soon Now for at least a year, and is in theory making progress, but I can't spend promises at the supermarket.
If capitalism works by selling people a piece of shit that barely does what it's supposed to do at launch, doesn't have mainline support, and is consigned to the dustbin after a single dev cycle or two because the manufacturer has moved on to the next piece of shit they will sell to the next mark and then abandon shortly thereafter, then I guess I'm anti-capitalism now. They tell me it used to be about making money by selling a decent product, rather than selling obsolescence-at-launch, thereby scamming people by design. I don't need that kind of capitalism, but there's a lot of it coming out of China these days.
