It’s even broader than that: historically most of the original protocols for the Internet were designed assuming people wouldn’t do bad things: for example the original e-mail protocol (SMTP) allowed anybody to connect to a an e-mail server using Telnet (a plain text, unencrypted remote comms terminal) and type a bunch of pretty si mple commands to send an e-mail as if they were any e-mail account on that domain (which was a great way for techies to prank their mates back when I was at Uni in the early 90s) and even now that a lot of it got tightenned we’re still suffering from problems like spam and phishing due to the “good faith” approach for designing what became one of the most used text communication protocol around.
