The internet and GPS, the core technologies of our time, are both direct descendants of the US military.
You may not like it, but the entire IT and tech field are built on US military tech
In ancient times both mercantile and military incentives propelled the design of ships. Is fair to say the whole ship building field built on military tech?
Even if it were true that in the distant past a thing had a military application/funding, there's no reason to use their terms for new things which aren't military in nature. No commercial liner calls it's full speed "military power". It's just cosplay at this point.
There's plenty of room to debate how much of our technology came from the military, but I don't think naming is a big deal.
Take the word "screen" for example. The original meaning was a partition to protect from heat. Many of these were fabric, and led to "magic lantern" shows done with shadows. The word was repurposed again for the projection era. And yet again for tube TV's and beyond.
If you told somebody from 100 years ago to look at the screen they would have no idea what you're talking about because the original meaning is lost.
That's why I don't think it matters whether we use military terms for computer stuff. It doesn't have its original meaning anymore.
Good, we agree, no more tacti-cool cosplaying in IT.
