I'm about as pro-capitalist, laissez-faire, pro-free-market as it gets. I was a literal card-carrying member of the LibertariaNZ party back in New Zealand. The spirit of this license disgusts me at a fairly deep emotional level.
That said, I think that this specific concern raised by the license is very real:
> ... If you want your code to empower students, artists, hobbyists, collectives, cooperatives and nonprofits to survive under capitalism while not contributing free labor to corporations.
I've seen a few cases where I think that open source authors and maintainers are getting it in the shorts. Yes there's value - "Egoboo", learning, personal promotion, etc. - but I don't think it's enough in many cases. For example:
* Free software that contributes to the growth and dominance of proprietary, for-profit ecosystems. E.g. I was recently back on Windows for the first time in a decade or so professionally, building an app I'd written in Common Lisp. Scoop (for package management on Windows) and Rosewell (which now supports Windows) made this super easy and pleasant. But ... why would you spend your time writing Free software to benefit such an ecosystem? Unless you're being paid for it, why not spend your time contributing to a Free ecosystem instead?
* Free software that is productised by cloud providers (e.g. https://www.zdnet.com/article/aws-hits-back-at-open-source-s...).
* Companies like Google, who are happy to build upon a plethora of open source products to generate billion-dollar profits, but who then turn around and actively give the middle finger to the communities without which they wouldn't exist (e.g. https://www.theregister.com/2019/04/03/googles_widevine_drm/).
