Arduino has four layers, only two were ever truly open:

1 Hardware reference designs (sort of open by intent)

2 Core software (open-source licensing)

3 Services and “happy path” tooling (not open)

4 Brand and governance (never open)

Qualcomm’s move is about owning layer 4 and using it to grow layer 3, while keeping layers 1 and 2 open enough to preserve credibility and community adoption.

That makes sense to me. Adafruit’s complaint relates to layer 3, right? Is Qualcomm changing the openness of layers 1 & 2 in meaningful ways that affect makers & hobbyists? And I guess layer 1 is PCB design, not [MC]PU design, right? Is that what you mean by ‘sort of’?
