The unspoken issue with these drones is the fact that they’re widely available and made up of commercial-off-the-shelf components. A guided missile requires expertise in chemistry, materials science, and a lot of expensive experimentation. You can’t fly under a government’s radar with them. A drone however, is accessible to every citizen, and the software that runs them is widely available and accessible.

In nuclear weapons it’s the difficulty in sourcing the nuclear material that prevents widespread proliferation. Imagine if the core could be made of something like iron, everyone would have nukes and our civilization would not survive.
