I'm talking about the general sentiment. You can see this on every* site, HN included. The litmus paper is that even pointing out something objectively true will get criticism (downvotes) rather than critical thinking. In the current atmosphere nobody asks the question when it comes to China/Russia/NK/Iran but will when it comes to the US despite the known history of hacking/spying on everyone else.
*Recently a reputable tech site wrote an article introducing DJI (ostensibly a company needing no introduction) as "Chinese-made drone app in Google Play spooks security researchers". One day later the same author wrote an article "Hackers actively exploit high-severity networking vulnerabilities" when referring to Cisco and F5. The difference in approach is quite staggering especially considering that Cisco is known to have been involved, even unwittingly, in the NSA exploits leaked in the past.
This highlights the sentiment mentioned above: people ask the question only when they feel comfortable that the answer reinforces their opinion.
The difference, in my opinion, is in the documentation and frequency of use. Is it overt? Does the customer really know its there, and what its for?
Perfectly fine to have an access panel that gives you access to the buss .. if the pilot knows you're doing it.
But if its some random entrance in the back of an alley, only 2 or 3 users in the universe know what it is and how to use it ..
