To add. all official published results must be done using "official analysis",
and for the purposes of this discussion, said "official analysis"
often runs exclusively on RedHat-flavour linuxes.

That has nothing to do with Linux and Red Hat. I do not know
why you bring it up. And you did not get it completely
right, either. In Physics, we do not have to sign legal NDAs
to participate in experiments and projects. It is basically
an honor system, and everybody plays by the rules
and/or breaks the rules per basic human nature. Books have
been written about this stuff.
