Well a hobbyist that took 4 years to develop his design so not just some dude who built something over a weekend. And by that logic a lot of countries could make ICBM nukes on their own - why don't we open source that technology since there's no reason not to share it since they already could probably figure it out.
So then what are the obvious reasons?
Hi, Im the creator of the video, Not that - the main reason was to prevent people with little experience blindly copying code onto a rocket without understanding what it does and then getting hurt/breaking their rocket and then blaming me. I did say you could contact me for the code, so this doesn't make much sense. Also, this is nothing close to a guided missile...
