Ok, just to look at the examples given...
Mojang doesnt count because it was an enigma. Rare gems like that happen once in a while. After all, look at Half Life 2 and Steam. Steam was originally conceived mostly just as DRM, but things took an unexpected turn.
If we look directly at Steam, well...Valve has done a major shift and is more a publisher now than a game developer. Anything that used Steam cannot claim to not have had a publisher, since that is exactly the role Valve/Steam is in. This same argument can be reused with any indie distribution platform, such as XBLA or Play Store.
Kickstarter is a publisher, period. They may do things a little differently, and in most cases leave distribution to the developer, but the publisher role is still there.
And Totem Arts...well, yeah they are indie and dont have a publisher. But, can you honestly say you would care if you had never been a fan of the original Renegade? When I told my friends, who are not CnC fans, about Renegade X, they were all pretty "meh". Im sure once they play the game that they will love it, but the promotion of the game is being done almost exclusively by the fans. This is true of many other large scale mods.
Again, publishers are here to stay and are a necessary evil so long as money needs to be made for game development.
As for the balanced gameplay discussion, it is actually curious that EA bought Westwood all the way back in 1998. That means that both Tiberiun Sun and Red Alert 2 were made afterwards. These still felt like Westwood games because they were made by the same people. When new people were brought in to develop everything afterwards, they were making games that they had no mental connection to, so I dont blame them.
Just to make it clear again, I dont like EA. Im not defending them. Im merely point out that they played a large role in the CnC history. Keep in mind, though, that blame rests just as much in Westwood as EA. After all, Westwood did sell out to EA. Maybe the majority of the peeps working for Westwood didnt want to, but it happened anyway. In the end, its always about the money...
