The idea you're trying to advance here is just plain silly.
You need your doctor more than your doctor needs you. That doesn't change the fact that your doctor is doing work for you, and not the other way around. Same for lawyers, plumbers, electricians, architects, and anyone else working in any number of other skilled professions.
Do you also engage in silly power plays to put your doctor in his/her place and remind them that they are working for you? Maybe you can insist that they use a 10 year old stethoscope or you else you'll take your business elsewhere.
Developer can switch jobs fairly easily. Its a sellers market. Companies that don’t understand this are going to wonder why they have a hard time retaining talent.
"Yep, we put those developers in their place."
"Hey, why are they leaving???"
"Oh, you mean we need developers more than they need us?"
