In all seriousness though (and this is a question that everyone should ask themselves semi-regularly in a product-consumer situation): why do you matter? If you don't have a compelling answer to this question, it may be that you don't.
The problem with people arguing about DRM is that fundamentally most people don't seem to care. Video games are a billion dollar industry, but non-DRM'd games are not.
You can vote with your wallet, but the data seems to indicate that your wallet is too small to matter.

It only should increase the incentive to avoid buying DRMed games, and specifically support those who aren't scared to release theirs DRM free.
For example look at the latest Humble Indie Bundle. Linux users pay highest average for the set. It shows that they encourage developers to produce Linux games more than users of other OSes (obviously since Linux games scene is lacking). You can argue, that Linux games market is miniscule, and if so, why even bother to send your message in such form? But you still see people showing appreciation, and developers can take note of this.
If we assume every bundle gets a total of a million dollars, shared between 5 games or so, that makes 200 000 per game, minus the donations to charity and the fees to the Humble Bundle organization. Let's say 150 000 dollars per game in the end. 15%-20% is 23 000 to 30 000 dollars, just for the Linux Port. If you are an small team of indie developpers, I'd say that is not negligible at the end of the day.
In my opinion Kickstarter (or grant) model is infinitely better, because it doesn't insist on treating a game like a physical object. The "selling software" model is horribly flawed. Writing software is like research - a big cost and effort once, then very little cost to benefit from it. It is fair to have effort of research/software development proportional to reward the researchers/devs are getting. With "selling software/drugs" it's not proportional.
