Is it maybe that not everybody holds your world view of what a band line up should be. I personally am quite relaxed about an evolving line up in any band and there have been a few global bands that have done just this. If this is a red line for you that is fine, but it's not for some of us.
For what it's worth I completely agree that BB was/is a far better drummer than AW, but I've only seen BB once with Yes and AW mulitple times so I associate him with the "classic" line up. What I choose to spend my hard-earned on is my decision, and if you believe I've been overcharged that's fine too, your choice not to go.
