Can we all agree a definition for "open source" when referring to SEs?
Open Source in my table means that firmware for specific secure element is released with open source code.
I won't nitpick and get into details with that, but there is a cleat difference between open source, closed source, and source verified.
Yes, but the clear message here is that it is the firmware that is open source, not the SE itself. I think that talk of "open source SEs" and the like is very misleading.
