So if it's all about he giving, why would GenCon not simply donate the money without asking for a logo? When I donate money to an organization, I ask for a tax receipt, not a logo. I don't go tooting my horn about how much I've donated to organization XYZ, I just give them the money quietly.
If you're reading between the lines, then how about asking why GenCon made a big stink about it? Or why they even bothered asking for CCF's logo? Or why CCF would've taken all those donations by the co-creator of D&D, if CCF is morally opposed to D&D (by the way, the concept that CCF might be morally opposed to D&D has been brought up by the various bloggers and article commenters while CCF itself clearly states that it is not).
The blogosphere is alive with cries of "How dare CCF call us evil? D&D isn't evil!" (or at least that sentiment). But looking through the actual correspondence that's been posted publicly, and CCF's public response, there's actually no indication of them calling D&D evil. In fact, they specifically state that they have no opinion of the game, good or evil.
So, thought-provoking? Yes, it makes me wonder at how completely over-sensitive D&D players are to imagined slights, and how the Internet helps spread their over-the-top responses to these imagined slights at amazing speeds. Meanwhile, the player-base continues to grow as kids of oldtime players get introduced to the game (as my oldest now has).
