It’s not a coincidence. It is actually an excellent example of how human memory is affected by the things we hear from others in a group.
Memory doesn’t really work like a picture or a book or a movie. It’s a fairly imperfect record, and it can change a lot over time. My memory is pretty decent, and I definitely misremember stuff–sometimes with great confidence
There’s very good documentation in the linked thread showing that the ETT is only there about half of the time from Find Recruits II. There’s absolutely no doubt that this is how it has worked for a very long time.
But it’s not surprising at all that your alliance, as a group, doesn’t remember this–memory is like that. And once one or two people say something, other people’s memories will tend drift to align with what they’re hearing. Especially if the statements are made confidently.
This is why when people say: “xxx has definitely been nerfed because many people say so,” I am always pretty cautious and ask for data.
