To make the same argument, but to point out the absurdity of your argument, GameStop (or other retailers) put up advertising for products on their window. This has a material cost. However, if you buy it from somewhere else they don’t pay for this cost.

Valve choosing to advertise is a choice they make. They can choose not to, but it makes them more money if they do. Other stores should not have to pay for a different store’s choices. That’s insane.

Edit: You love to see the downvotes purely out of spite I guess. No one is presenting a counter to this view, but we can’t criticize Valve now, can we? That’d be wrong, because they’re a good corporation making billions in profit, unlike those other corporations!

If you’re thinking of downvoting, leave a message about why this comment is wrong if you don’t mind. If I made a mistake, I’d love to correct it.
