This is actually is an interesting example, because Cities Skylines 2 has been handed over from Colossal Order to Iceflake Studios recently and since then they have (in my opinion) quickly been able to improve and fix a lot of things that CO weren't able pull off for years. So perhaps CO's development was somewhat of a "total shit show"?

I'm not saying Unity should publish PR about how Unity is working well and this handover and subsequent fixes proves it, but I think you could argue that they could and that they would have at least some facts to back it up with.
