Serious Sam is a wicked gahbidge series for chowdaheads.
Because it was made available for free/really cheap and you should have gotten it before. On the same hand, i'm not your servant and I shouldn't have to give you stuff for free even though I have it twice.
Sure, I can easily give it to somebody if I so desire, which I usually do, but why can't we trade things? If you're willing to pay full price, then just buy the game from Steam, why would you buy it from me?
So why not try to recoup half the normal cost then? 15 or 10 for Saints Row 3 would be a good deal for the person trading. You're right: you've no obligation to provide anyone anything. So why do you only try to get 2.50 for a key? Why are you only allowing yourself to make a tiny profit off it?
And why is that different than a person trying to make a full profit off it? The scale of it?
The truth is most people see someone trying to flip a Humble key as a scuzzy move for a number of reasons, one of them being that there is no way to discern if you bought the key for a dollar (unless it's a beat the average key), another being that there is a charitable component to Humble specifically. Why do you have to get remuneration for your unused key? It's a digital product: it doesn't sit there rotting.
