While companies backing out sucks, this is a downward spiral.

If companies get wind of candidates doing this in mass, they can escalate the game even further.

That is, make offers to candidates and continue to shop for better candidates, knowing they can just pull the rug from the first set.

This game will be lose-lose.

Isn't it already like this though?

Most companies won't do that by default, but when push comes to shove, they care about the bottom line much more than the person. Plus they have almost all of the leverage.

I agree with the GP because the power imbalance is too big. They're also not saying people should screw companies over all the time. Just to not feel guilty if/when it makes sense to take a better offer.
