And yes, a major complaint of mine is using C or C++ when you don't absolutely have to.
You mean lack of Algol, Mesa, Modula-2, Modula-3, Ada, Oberon, Oberon-2, Component Pascal, Object Pascal, Delphi, .... ?
C became ubiquous when UNIX got adopted as the enterprise OS, slowly replacing the mainframes.
Like JavaScript in browsers or Objective-C in iOS, targeting UNIX meant using C, back in the day companies would pay for UNIX SDKs.
No sane company would buy another compiler when they already had to pay for a C one, the official language.
The other OS vendors started to offer C compilers in their tools to ease the transition between the new UNIX workstations and their other OS.
So alternative saner systems programming languages wither way as C grew stronger and now we are with this problem.
What I meant was that, after the spread of Unix and C, C is the most common systems language in production. (Before the spread of C, I believe assembly was the most common systems language(s).)
I suspect that any systems language would have a bad reputation if it were used (and over-used) as much as C.
Examples of dangerous UB in C always use deliberately sloppy code for pedagogical reasons. For real-world examples of problems, look at the CVE database.
