The parent's post is wrong on so many levels. Let's start with the technical:
1. Most multi-rotor toys which are bought from anywhere more dedicated to the hobby than toys-r-us ARE drones. Can it go by itself? A lot of people will answer no, and yet when their controllers drop out the drone (and I will keep using that word) will return to launch, or hold position. Most entry level drones are controlled via GPS and barometrics. That is how the hobby has suddenly taken off to thousands upon thousands of unskilled fliers. The ability for it to not just fall out of the sky when you're not paying complete attention to me implies a certain amount of autonomy.
Then there's the hobby and the use of the devices themselves. Yes I fly mine with controls, sometimes I even fly it fully manual. But typically when I finish I just flip a switch and meet my drone back at my car. My drone was hyper expensive, a whole whopping $500. Yep that's right, it's usually one of the cheapest toys in the local park. But that is how I CHOOSE to fly it. I can just as easily load up software on my phone and via telemetry send it a flight path and hit go, but where's the fun in that. Done it once and it was boring. It doesn't make my drone any less of a drone when I send it commands continuously.
2. Then there's your grasp of English. Despite what you think drone means, we have dictionaries for a reason:
drone noun (AIRCRAFT)
a type of aircraft that does not have a pilot but is controlled by someone on the ground
But even if we ignore the dictionaries, most of these toys over about $120 come with some sort of FPV system now. The FAA defines these as drones too.
Just because the word drone started off as expensive military toys, doesn't mean that a device which has the same features (remote operation, most drones were never autonomous) isn't worthy of the title.
