I suppose this was bound to happen eventually. Well, at least I got one more non-Steam DLC. I got EUIV as a show of support for the Islamic DLC, so I might conceivably install the free copy of CK2 Steam if you come up with some amazing DLC I absolutely must have, but more likely I'll just leave it and move on. Thankfully, I can continue to find non-Steam games from other companies.
Hopefully in the future it will again become economically sensible for you to offer non-Steam versions of games. For those who love Steam, enjoy, and try not to write excitable tracts about the virtues of a digital content provider that you like and I don't.
