It's kind of like how when selling a house your optimal strategy is rarely to try to appeal to the most people. Instead, modifications which greatly increase perceived value in a smaller subset (so long as it isn't too small for your personal goals) will alienate most customers but still increase the sale value in the same timespan.

When you're applying for jobs, some companies aren't willing to play that game, and if you're playing it then that's not just fine; it's ideal. You don't waste your time on companies who won't play ball. Enough will that the strategy still works.
