I haven't worked in aviation so my understanding of terminology could be wrong, but either way it is definitely an unusual example.
I don't know of any evidence to say either method is objectively better. By removing the situation from their thoughts/avoiding the topic they may be able to cope for just as long or longer than someone who addresses the situation through comedy.
An argument may exist for lint etc being harder to clean out of a USB-C port once it had made its way in there, but haven't witnessed it myself yet.
Anecdotes can be given all day, but I would suggest it's a potential problem for any port of similar size being placed in pockets and bags.
As a further point, drivers are (with edge case exceptions) not kept away or locked down from performing any work on their vehicle, yet in most cases they would still prefer to pass the responsibility on to a trusted professional.
I believe the same is the case with limited control over technology. Most users do not care to learn, and would opt to actively avoid the opportunity to learn if the associated danger was removed for them.
In my opinion the best option is to remain in the current state by default and have a more obscure 'power user' option that could be enabled within the OS itself.
In addition Australian's are known to be coffee snobs, anecdotally I've found even those that are not big coffee drinkers tend to be quite particular about the taste of their coffee.
If coffee roasting and preparation is held in high value and seen as somewhat of a craft it makes sense for Australian's to hold loyalty to particular roasters/baristas/cafe's. To draw a parallel, when getting a haircut many people will return to the same person if they are happy with the experience/result.
Ethics are commonly a "system of moral principles", said system and principles being the reasoning behind ethics.
I'm assuming what you are trying to say is that "ethics are not absolute", which has strong arguments; however, I think the critique of the use of "unethical" is partially in agreement with my assumption of your first point ("ethics are not absolute"). Assuming ethics are not absolute, then labeling something as unethical in a blanket statement would not always hold true.
I would suggest simply prefacing the statement with "I/many believe" would sit more comfortably.
