Two ways of looking at everything.
The photographer chose to sell his photos on that site. If he hadn't have done that, somebody else would have got Time's $30, and the potential boost that he can now give his business by having one of his original photos on their cover, would have been somebody else's windfall.
It's not something to cry about, Time clearly no longer want to pay $10k for a cover photo, and he now has a great opportunity to trade on this.
Up to him how much he ends up benefitting.
