I agree with you to some extent, but I can't ignore all the feedback and lessons from Humankind. That's 5 years of clear community input they completely ignored. I genuinely believe they could have reworked the civ-swapping and era change mechanics in that time. Some people claim they couldn't, but even if we assume that's true, they should have at least acknowledged the issue and prepared for a potentially bad reception or a fix in the form of a classic mode (keep the same civ). They did nothing.
What worries me is the lack of internal pushback or awareness. It feels like they keep making the games smaller and simpler. Maybe it's 2K, maybe it's Sid Meier or maybe it's Ed Beach. For me personally I can say that 2K and Sid Meier has previously made civ games I like - and Ed has not. There's certainly talent at Firaxis, but they have a hard time listening to feedback or looking at other games.
At least they should have known that it would be a problem.
