Unrelated to drones (but is a hardware/software manufacturer)- I would like to call out Axis (as an Axis network cameras) as one of the rare positive lights in this mess. They clearly state how long their products will be software supported, and they stick to that minimum and frequently go well beyond that minimum.

Axis has products that are over 10 years old that still receive frequent security only firmware updates. If they can do it across hundreds of different hardware products, then these companies can too. (in fact, Axis was doing it well before this became a main stream issue)
