Honestly, I'm surprised you get told off a lot. My own subjective experience is the polar opposite :-)
As a Linux desktop dev, getting hung out to dry over this in HN threads is my usual experience, and it's pretty frustrating and dispiriting. People tend to take the free output of FOSS communities for granted a lot and have zero inhibitions at heaving ridicule or even more mean-spirited things at your work output - especially at HN as a "how to make money with tech" forum where the non-profits rank fairly low in the hierarchy.
I'm still surprised at how prevalent this is in the HN setting however. FOSS is generally not popular on HN, but a lot of HN posters also style themselves as founders, leaders, business developers, side project-ers. Yet despite this outlook the debate very rarely takes a can-do constructive perspective a la "How do we make large FOSS communities better at this area of SW eng?" or "How can we develop this capability in this paradigm", etc. as you would maybe except.
Instead the discourse rarely rises above the level of just asssuming devs are dumb or lack essential capabilities, which is bold about a generally fairly smart and intrinsically motivated demographic.
