If that was 2015 or 2010 then I'd say: why would people competent in computer vision waste time on making 30$ cheats when they can use their skills at faang for probably 200k?

Because they are kids and they use it as a practice ground to gain those skills inadvertently. Or they use it as a practice ground where they don't have to deal with bigtech BS and can just develop with no design reviews and all the miles of BS getting in your way.
