So you didn't mind NFZ updates as part of firmware updates. Do you check the NFZ database for each firmware update to make sure that it was accurate before installing it? You wait until other people test the firmware for you before updating, and you think that is going to validate the NFZ database in the firmware?
In terms of how the NFZs cope with Part 107 vs. Part 101, that issue is unchanged whether the database is dynamic or locked to firmware versions.
The rest of your objections, in my view, reflect either irrational and over-imaginative fearfulness and/or a very skewed view of technology. For example, as
@Meta4 said earlier, try applying that logic to your mobile phone, of example. That could be rendered immediately useless if hackers successfully attack your cell phone company databases.
Personally I think that you are hugely overreaching in an attempt to justify an illogical objection to a minor change in how the NFZ system works, not even because you can find anything wrong with the database, but because you are scared that DJI might get it wrong in the future in a way that might, possibly, inconvenience you. But if that is what you want to spend your time worrying about then fine - your prerogative and not my problem.
