A little tangential, but I didn't know there was a utility called `finger`. Is this supposed to be a profile directory envisioned for an Internet back when it was more decentralized?
I think the tendency to take anything, in nearly any context, that could even maybe be vulgar, as vulgar 100% of the time, is actually relatively recent.
What may make it seem to be changing is that society (or more particularly, white-collar workers & pop culture) has gotten far less formal than it used to be. Even non-tech companies are moving away from suits as required office attire, the only professionals I know personally who still wear suits to the office are lawyers or in the financial industry (which have always had a conservative, slow to change reputation).
Edit: typos & formatting
In a way, it cheapens the phrase 'double entendre', as AFAIK the phrase used to imply a clever, sometimes obscure, double meaning that was intentional vs. anything that could be taken out of context.
Or, as Archer would say, PHRASING!
