I do not plead guilty to muddled thinking nor am I concerned about
programmers' understanding about Boolean Logic.

A C programmer can make exactly the same argument that he/she has to
evaluate an expression and then read two additional lines to understand
what the outcome was if the initial complex expressions are expanded
(a.k.a. made long winded).

  // z = x++ + y++;
   z = x + y;
   x++;
   y++;

  // z = x++ + ++y;
  ++y;
  z = x + y;
  x++;

  // z = ++x + y++;
  ++x;
  z = x + y;
  y++;

  //z = ++x + ++y;
  ++y;
  ++x;
  z = x + y;

But which forms best express what the program writer intended?

Good program readability is important whatever the language which is
being used and anything which enhances it is to be welcomed and anything
which detracts from it is to be discouraged.

This is of course only an opinion. But I see no point in tut-tut-ing
about the deficiencies and obscurities of C, and then falling into the
same trap myself.
