I’m running NixOS and my entire desktop environment is installed and managed without root.

There is only a couple of Dominos in Sweden, on the west coast. Visited one in Gothenburg a couple of years ago. Dunkin went bankrupt and left.

Not at all a stupid question. Answering from a perspective of flying fpv drones recreationally for 4-5 years.

Videos look analog because they most often are. These fpv drones are using very similar if not identical equipment as recreational commercial fpv drones. Analog fpv is a lot simpler, cheaper and easier to get hold of in large quantities, the latter is probably the largest driving factor as they are using the drones as disposable ammunition. Image quality is worse but is probably good enough for the most part.
