Honestly I did read that as "Employers who are married to their job are the best employers". You probably won't treat them like shit, but they'll still remain married anyway.
But such employees will sometimes leave and build their own stuff. Which they'll very likely succeed at, exactly because of the approach they have.
Ultimately, I think these are a bit different fields/markets, and a bit different kind of jobs. Engineers creating real unique new stuff, vs more "bland" engineers just being a hand to accelerate someone's efforts. I worked in both roles and can clearly see pros and cons of both. Largely depends also on life phase one's at, which one would a person prefer.
