You quoted HanNorwood, who said:
"With Tides of Power coming with a pretty hefty refinement of naval systems in CIV VII, I am really intrigued by the possibility of future DLCs being the same."
Your response was:
"Off course they will put stuff in a paid dlc that should be a patch for the main game.
"oh look, buy our religion dlc to get your religion overhauled" etc etc."
HanNorwood was talking about Tides of Power, and consequently also any future DLC. You replied to them, about what they were talking about.
I've already said if you're worried about them reserving mechanical updates for paid DLC, I understand. But at no point has Firaxis locked core feature overhauls behind DLC. DLC content has been reserved for new, not changed features. So the evidence isn't on the side of fearmongering, here.
