Yes, given human nature you probably are right. I believe that the problem started with the monetization of the Internet in the early 1990s. Ironically the old 140 year old POTS phone system is now more “free” than the present Internet.
Even clumsy programming. We don’t need the malicious hacker to look for what happens if nobody locks their door. Enough that the drunk neighbor stumbles into your house and passes out on your bed.
