The term "Hack" has been used to represent dishonest, illegitimate or otherwise unsavory goings on for many many years! Taxicabs were called 'hacks' when they were illegal - IOW - No medallion..
Actually, when I first started messing around with computers in the early 1980s, nobody called software piracy 'hacks'. It was called 'piracy'! I used to disassemble programs that were key or password protected routinely. I'd just install a couple jumps around the offending 'protection' logic, and viola! I had a working program with no password or software key protection. I was immersed in that stuff for years, and nobody EVER called it 'hacking'. It was called Software Piracy. In fact, some friends and I used to have a small group that we called PUG which of course stood for Pirate User Group! ;)
Somewhere in the late 90s or perhaps the early 2000s I started hearing the term 'hack'... Nowadays it's used by everyone to represent anything! Anyone who's spent more than 11 seconds on any social media such as facebook knows that there are forumula sites out there that tease users with some tidbit of information, force the user to click through 17 pages of commercials before you get the payoff which is usually a huge letdown. Many of these are using the 'hack' term for anything that repurposes something. (E.G. Turning a plastic water bottle into a solar panel that will start a diesel truck)
It's all rather silly... Everything is so formula today! Doesn't ANYONE have an idea of their own? ;)
