>they think capitalism is inherently evil

Modern society has done a wonderful job proving that sentiment right. I can't blame them.

>would prefer if everyone was just poor and lived in the woods or something.

I'd prefer if everyone had proper control over the tools they used. Whether they choose to live in the woods to use such tools or use them to make society a worse place is the double edged of 'free' (as in freedom)

I completely understand those skeptical about perverse incentives from not making software 'free' (as in beer). It shouldn't be a surprise that adding monetary inventice changes the entire incentive structure.
