If the company currently employing the employee is weakened more by that person leaving than they would've been by paying them enough to stay, it's just bad business to have paid any less. You don't own your employees: they're free to leave for better offers at any time. Giving a better offer is just part of running a business and making deals, not "poaching." I can't feel sorry for companies that underpay and then get harmed for it; it's dumb and they deserve to lose.
