This is something that always irked me about RPi's. How the fuck, you, the hardware vendor, that's suppose to know the inner guts of your product, do not have full production for its software? That you need it to rely on undisclosed 3rd party blobs!! Yes, yes, I know about the politics and the business logic that led to this situation but that was at beginning, when money were need it. Nowadays they are in a good place in that regard, might wanna pivot so they fully control everything, but I guess once you go with a bad design, the complacent around that just grows.
