It is what it is. You have to remember two things:

1) A lot of people are not allowed by their employer to buy F.
2) A lot of travelers (or their agents) buy whatever fare is presented and allowable.

But, yes, the more you know about airline pricing, the more annoyed and/or pleased one can get. I'd be annoyed that I had to go through that, but pleased I didn't get shafted. It's your own knowledge and curiosity that is taking you down the path to frustration.
