In the late 80s/early 90s hacker became much less someone doing coding stuff for fun and much more someone trying to break into systems. The main mailing list for TeX related stuff, for example was called TeXHaX and no one assumed people were trying to use TeX to break into the NSA. Similarly, the online space for Perl folks was Perl Hackers (although I see that putting “Perl Hackers” into Google mostly gives results about using Perl as a hacking in the sense of breaking into systems sense and less the programming for the joy of it).

Another word whose change in meaning over the years has resulted in its original sense being effectively erased.
