$100 is not a huge amount of money to me. It's okay if it's not a lot of money to you either. Being rich and having privilege is not a crime -- however, being oblivious and insensitive is a crime, or at least unethical. You should own your privilege: understand what that means and understand that others have much less or much more.
As game designers, you should already know that it doesn't matter what a rule was intended to do. It matters what a rule actually does.
And when a lot of indies are brave enough to admit they're poor, and say that this rule discourages them from submitting to Steam for their best / only chance at some semblance of financial security based on their very good and deserving work (look at any indie's released sales numbers and the pie chart looks like Pac-Man with a nearly closed mouth; that is Steam's market share) -- when they say they are in pain, I am not going to tell them their pain is their own fault, or that their pain is imaginary, or that they're better off with their pain anyway.
Poor people deserve to make and profit from games too.
So please don't shut people out, because that's just one more door we'll have to kick down.
