I think you're confusing 'embedded industry' with 'embedded hobbyists', because we (the industry) don't focus on hobbyists.
The RPi really does suck from a professional use-case: no volume, no 10 year guarantee, no proper industrial certifications and until a few years ago, extremely bad integration with tools like Yocto.
The two segments do overlap sometimes, but it's definitely not the same beast. A lot of SBC vendors have provided great boards over the years (looking at Variscite, PHYTEC, Toradex, SECO et al), but the incentives, and thus the final product, are not what hobbyists expect.
