This sort of "I could do it myself, cheaper" reaction is pretty common for a lot of things posted on hn. I think it's natural for people (and especially hackers) to have this sort of reaction, I think we must be a lot better at analyzing dollar figures than time investments.
And frankly, it's not a bad impulse to have. We're not all generating income every waking moment. People do have free time they can use to build things for fun.
I'm not even really that big a fan of this design (doesn't really seem to have the ability to switch to sitting without disassembly), but I just don't like seeing things pooh-pooh'd because they cost more than something some of us could do ourselves.

Works for people around 5'9.
--EDIT-- After messaging the team, they say a router, some wood, and some elbow grease is all that should be required.
Why not sell a jig with instructions on how to build the desk, use a $90 router plus materials and create an instant crowdsourced mini standing desk factory? If I make one, I could easily make 5 more in probably half the time. And given the ease of manufacture, I have an almost zero risk chance to learn a new skill.
Sell the franchise (the jig plus instructions) and then others who just want the desk can pay the maker (at the source) an extra $20.
BTW, this design doesn't look stable enough. Needs either a tension wire or a wall support in the front and back.
Walk out with a new piece of furniture they made themselves but didn't require the huge upfront cost of tools etc.
