Im sure you could find a usb c camera that could easily be obscured or pinned to a lapel or otherwise disguised for cheaper than the price of a pair of smart glasses, or even just wear your phone on a lanyard around your neck with the screen facing your chest. People might think its weird but noone is going to second guess it unless your phone is in your hands actively pointing at them.
But you expect other people to use their free (literally unpaid) time to code what you want them to rather than what they care about or think is important. After theyve already made all of their work and progress free and openly available to anyone who wants to build off it. You have a fucked up view of the world.
