Nix is a software project, not a social movement. The goals of Nix are entirely separate from how the software is used.
I really like Coinbase's statement that is is mission focused (https://www.coinbase.com/en-ca/blog/coinbase-is-a-mission-fo...). Anything that isn't directly related to its mission is out-of-scope. I wish the same was true about software projects like Nix.
If you care about the way your software is used, then by all means, say it in the license! Of course, such software won't get used much.
Upholding the status quo is a social (and political) movement, it's just the most popular and accepted one.
Do you eat food, drink coffee, chocolate. Do you avail yourself of modern pharmacology. Everything you do upholds a status quo of human suffering. You posting on HN is a political statement, from a place of privilege, by that rational.
It's a software project, dont make it political and it will be successful.
