You aren't wrong but you're not entirely right.
There are countries where drones are 100% banned and others where their use is severely curtailed. That has restricted or closed those markets to DJI. If they introduced a model in Morocco, for example, that was incapable of flying higher than say 100 feet or 300 feet away, coupled with software controls (NFZs etc..) that prevented their use near or over any building or built-up area, it's just possible the authorities might reopen the market to them.
In other countries they are struggling to ensure they aren't seen as a danger of any sort, hence their rapid response to this issue. I mean think about it, since when did anyone in China give a flying toss about what people did with their products?
This is about nothing more than protecting their own interests and staving off the likelihood of a ban or restrictions that would throttle their business, so they will always try and remain in pace with, if not ahead of, administrative opinions and policies.
Think too what a marvellous source of intelligence all this NFZ data is to them (or "other parties") I'm sure a lot of it is public domain but hey, having detailed mapping like that, constantly updated....
It's a bit like when Huawei offered to install a complete WiFi infrastructure on the London Underground for the Olympics... completely free of charge.... In five minutes they'd have had every corporate network in the city under surveillance!
