Skepticism about the father's claim was a mistake, but it's not an inconceivable mistake to me. After anyone at OfficeMax had realized that the allegation was true, my ideal state of the world is that the CEO is on the phone within 5 minutes.
This is getting conflated with two other issues:
"Did OfficeMax actually intend to send this letter?" No. Of course not.
"Does OfficeMax having created a system which allows this letter to get sent mean that OfficeMax should fix the system?" Yes, OfficeMax should identify and fix the bug which allowed this to happen. In contrast to many people, I believe that the type of bug which caused this is likely rather minor. I would not agree that e.g. this letter is by itself a persuasive case that direct mail is evil, for example.
Somewhere along the line we got the idea that nothing negative must happen to us, and if it is, it's the worst thing ever. We're not that fragile. It's not a nice experience, but neither is it life-destroying.
Now lets imagine that the agency I worked for was sold/aquired at some point and eventually resulted in a mailout being performed on the database.
You can imagine the result if the comment field was accidentally included in the mail-merge, or some substring of it;
"Dear Great candidate, gap in work history due to marriage. Now divorced and wanting to get back get back into the industry, have you considered funeral insurance?"
Pattio11's point is quite valid.
