Did you read the thread? The entire situation has been laid out in bits and pieces over many posts, but it's all there and pretty clear:
- This change is taking place because of new requirements in China -- and ONLY China. I don't know the legal particulars, but I expect this is in response to some law/regulation going into effect in China.
- Users who reside in China will be required to re-authorize their DJI drones every three months by going through the login process with the DJI servers. Users outside China are required to re-authorize one time.
- The authorization requirement will be enforced by limiting drone functionality as follows: No live streaming video (FPV), range limited to 100m (330ft), height 30m (100ft). Users outside China are not affected by these limitations. [but what if they fail to perform the one-time re-authorization? This is unclear)
- The performance/functionality limitations require updating to a later firmware version than .400, which has now been removed from available firmwares in DJI Assistant 2; however there is a Virtual Machine snapshot created by member @adiru (props ) that can be used to downgrade to .400, currently believed to be the last firmware without the crippling capability.
- DJI quite understandably is keeping a single firmware implementation and version for each drone, rather than starting to branch to multiple versions needing to be supported. Anyone here who's worked in software development knows the nightmare, and impracticality of doing anything that idiotic in software management.
So, what can we conclude from a sober, calm analysis of what's going on? Simply this: China is requiring these capabilities to aid authorities, so DJI has implemented these features. They are activating them and using them in China.
My heart and spirit goes out to you, my Chinese brothers and sisters!
However, the hysteria over rather extreme, and very unlikely uses of these features in the US, in particular, and other "Western" nations is quite overblown. For good reasons DJI releases firmware world-wide, rather than trying to manage the nightmare of country-specific code branches. Instead, the generic functionality is implemented, and then turned on and configured where local law requires it.
This looks exactly like what DJI is doing.
Can the worst fears expressed in this thread occur with these new features? Yes, of course! That doesn't mean it ever will, however, and believing it's certain, or likely, is quite a stretch with no other facts or evidence of anything.
Like something from the FAA, connected to this. There ain't.
So everyone calm down, and wait and see what happens. If you're concerned, downgrade to .400.
I'm staying there for the time being too. But whatever you do, relax if you're not in China -- this will have no effect on you. If you're in China, sorry to say, it will, and it sucks.
