WTF are you talking about?
If any, science today it's made thanks to FLOSS software, propietary software it's the exception. And the trend it looking worse for propietary environments.
Money will come from support and integration, not for the software.
A complex, scientific related reproducible ad-hoc environment for Guix may cost a little more on a single PC than a a propietary OS license and setting up the rest for yourself, but you will be able to replicate that setup everywhere and forever and on a guaranteed basis that once your paper/experiment it's replicated, yo get the same environment no matter where and how. That's the difference.
