Strictly speaking coders are not engineers. We use that term colloquially but I definitely got the impression that the article was speaking primarily of PEs.
Very few engineers of any sort are PEs, at least in the US. Whether you are a classical mechanical/electrical engineer, or a coder, seems to be purely a subjective distinction. Some coders I know are definitely engineers, some are not (by my world view).
I think the article applies to any of the above, but the cited examples may be the domain of PEs - which as stated in the article - are not funded at all like corporate engineers, and thus have concerns more relevant to their funding model. Plenty of coders are involved in making missiles, and in fact some distruptive things (like bitcoin) were created by coders. There are huge ramifications to bitcoin, should it become successful: tax evasion, illegal trug trafficking, import/export bypass, etc. All things our government was asked to interfere with, by someone, for some reason, that are bypassed by someone's experiment. You may not support "the war on drugs", but the freely elected government of the US chose to take it on in response to various pressures. There are ethical implications to providing a mechanism to easily bypass this to others.
This topic always comes up, but the bottom line is: if it can be done, someone will do it. The world is not populated by exclusively ethical people, engineers are no different. Having a thing and then choosing not to use it probably causes less actual destruction than not having it at all.
