I am as equally as surprised by their surprise about how much R&D is involved in making a "simple" lamp. Someone had to draw the plans so that the metal/plastic could be formed/shaped into the lamp. The parts had to be researched on what could suffice and be safe. Some person didn't just go "i want to make a lamp" and a lamp was created (unless they had Aladdin's lamp first). Research can be as simple as internet searching on parts, but that is still research even if people with PhDs and white lab coats were not involved. The design is still necessary in getting the lamp to a shape that is aesthetically pleasing enough for someone to want to buy it.

>Woodworkers don't market their plans as open source, put them on Github, and accept pull requests.

That's not true in the spirit to the point you are making. There are plenty of websites where wood workers offer their plans/drawings/instructions, and then allow comments where people that followed their plans made modifications. So yes, they don't necessarily use Git and PRs, but the concept is there nonetheless. Same with cooking/baking/etc.

You're reading into the comment an emotion that did not exist when the message was sent. If you read hostility, then that's no what I was trying to infer.
