For instance, there could be a community-made script that fetches the latest Foundation Passport source, removes the games and compiles it.
Even more risk then, since you are trusting the Passport developers not to introduce a vulnerability with their stupid games, and then trusting the community not to introduce a vulnerability with their code to remove said stupid games. And the community driven version won't be pen tested to the same degree as the native version.
It's such a pointless edition, I cannot understand why they implemented it in the first place. It makes them seem very amateurish.
For example, Shift Crypto offers a 'Bitcoin only' firmware that I believe can also be flashed to the 'Multi' edition (irreversibly).
True, but Shift Crypto also developed AOPP, so they are off the table as far as I'm concerned.
