What I think should instead be evaluated is how effective that investment into the FSF can be.
I think we also need to think more strategically here. For instance, LibreOffice should really receive a lot more funding and support by states all across this planet. I am tired of the US monopoly (almost a monopoly) here (Microsoft).
I was looking into shared key encryption, found Shamir's Secret Sharing algorithm, found a GNU implementation called ssss.
Thank GNU
In fact, the trend is to move away from GNU. Clang over GCC, musl over glibc, uutils over coreutils, etc...
The FSF has an extremist position. Not only they promote free software, but they also don't want proprietary software to even be an option. For instance Debian is not up to their standards because they have optional repositories for nonfree software. I can't imagine Amazon supporting such an organization.
