@gnurp This is a really good point, but I think it shows that exports/arms control was never the right solution.
There is a lot more that can be used as deadly weapons than only a drone with a raspberry pi. Cars, heavy machinery to even common household items like knifes. Legally sometimes even boots count as weapons.
And still we don't heavily restrict the access to these items. But we solve this problem with a societal contract that the application of violence is wrong.
The access to a raspberry pi and ardupilot isn't the problem here. It's people (sometimes with orange skin and small hands) normalizing violence as a means to achieve their goals.
