Just to reinforce what another commentor said, Pis were still being made available to sectors like business and education, so vendors who built products around rpi were still able to operate. We worked on a project in 2021 where we needed around 150 and had no problem sourcing them from a single vendor at MSRP alongside their product.

Of course, that's not what I expected since I'd been personally affected by the shortage to retail, and because the others weren't aware of that, I probably looked worried over nothing when I suggested we explore other SBCs.
