Yeah. I once hiked 11 miles in the desert on a road trip to film a specific shot and when I unpacked my drone I found out that the app had updated overnight and needed me to log back in before I could fly again.

The nearest cell service was 30 miles away.

Edit: And the next drone I bought was a DJI, because nobody else comes close.

There are tons and tons of excellent drones running opensource betaflight so I challenge your claim that all 'no-name' drones are bad. The top racers and freestylers and world-record-speed-setters don't fly DJI and I'm pretty sure the market for professional cinelifters is entirely out of DJI's reach. It's true that there aren't really other drones in the same market segment with all the hand-holding and flight assist and outright auto-flying DJI is famous for but that's a much more narrow window. For people who want that stuff your claim is true.

For people flying primarily with their own skill there is still a great opportunity to build from parts and compile from source.
