It’s also accounted for almost 100% by mosquitos, specifically the diseases they carry…so not really the mosquitos at all. Quick searching shows snakes following mosquitos with 100,000 deaths caused per year. In any case, the scale is prodigiously unbalanced. Human animals kill trillions of non-human animals, almost entirely for their own pleasure. Non-human animals kill a few hundred thousand human animals (or a bit over a million if you count mosquito-borne disease) in self defense or by accident.
There are tons and tons of excellent drones running opensource betaflight so I challenge your claim that all ‘no-name’ drones are bad. The top racers and freestylers and world-record-speed-setters don’t fly DJI and I’m pretty sure the market for professional cinelifters is entirely out of DJI’s reach. It’s true that there aren’t really other drones in the same market segment with all the hand-holding and flight assist and outright auto-flying DJI is famous for but that’s a much more narrow window. For people who want that stuff your claim is true.
For people flying primarily with their own skill there is still a great opportunity to build from parts and compile from source.
