That's not accurate though, is it? Unless you're exaggerating for effect.
I don't think most people on HN are against non-free products at all. I think they're against products that provide little value compared to their price.
There may also be some general exhaustion from so many products moving to a subscription model, instead of an old-fashioned one-off purchase. $9/month may not seem a lot, but it quickly adds up.
Sure there are zealots on both sides and they always tend to be the loudest voices in the room but over all, I find that premium products offering value and not just rebranding otherwise free products are met with positivity.
I think it's interesting how the same thing can appear so different, depending on who is looking.
That’s the hot matter! Value expected for $0.30/day, just taking from the comment above, as the most common price point?
Eg. Someone makes and shares a WP theme for free, then another person comes along, changes the font size and lists it as a premium theme. Even worse another person pays the 2 bucks for the "Premium Theme" then rents it out to a unsuspecting customer who builds their own WP site and pays the company a recurring 0.30/day or 10$ monthly fee for using said theme.
No value added just parasitic marketing.
Non-free (as in freedom) software is not something that any self-respecting programmer would willfully associate with because it's inherently dirty. A proprietary license is (literally) a form of DRM. It's a feature that is hostile towards its users, especially those who are "makers" or "doers."
