For what it's worth, I had the same reaction as you. The still image of the YouTube video prominently features a woman standing, arms spread, with her nipples clearly visible because she's not wearing a bra under her shirt. Other comments here shed some light on this. Apparently the original creator was aiming to create a system that managed the wires under her desk, and named it underwire. An underwire is a part of some bras, which is how they got to the suggestive branding. It looks like this is version 2.0 of the project / a fork of the project so they changed the name slightly to underware, as in 'hardware under your desk, to manage wires' So it's a bit off for me (use sex to sell beer; tell me I'm smart to sell nerd stuff) but at least it makes sense now. Hope that helps!
