I am exaggerating my reaction, but I honestly don't really care about how accomplished leaders are. If they had an interesting impact or story in their own right, they're a fun choice. My dream roster would swap out Augustus for Tarquinius Priscus, Catherine for Rasputin, Napoleon for Haussmann, and... well, Franklin and Tubman are already up my alley, aren't they? Exchanging Ben for W.E.B. DeBois would be tempting, though... I can safely that "new and exciting picks" are not just a way of holding series staples hostage and that they do indeed appeal to a section of the fanbase... because I am one of those fans.
As the article addresses and as the changes made in VII have made clear, a lot of us have very different ideas of what Civ should be. It may seem to you that a pack including Britain and Simon Bolivar along with Nepal and Lovelace is trying to draw out content, but I'm having an opposite experience, forced to buy the (in my view) overdone Genghis Khan to get the Qajars. Some people want to see Gandhi, Canada, or Venice added as soon as possible, while my dream DLC pack would have Tonga, Maori, Nazca, and Kilwa Kisiwani. To many, Europe is criminally underpopulated in the base game. Personally, I would have preferred to see Russia or Prussia or France cut out to get another continent closer to "complete." The developers have to balance the sects of the community that have these contradictory desires (as Mr. Beach is getting at in the article), so not everyone gets exactly what they want, but it's not like the sole purpose is to offend your sensibilities specifically, it's just what happens with such a wide playerbase. To someone with your preferences, the game might not be complete until it has Alexander the Great. To me, such an inclusion is just an unfortunate sacrifice of resources demanded by tradition. I feel kinda bad saying this, but I struggle to sympathize with your concerns because I know that if the developers lean into them, I'm less likely to see the content I like.
