Right, but the 100k is just a sign up bonus. Once it hits, it becomes irrelevant to the renewal decision. When I make a keep/cancel decision, I don't care what the sign up incentive was, and I'd bet many people feel the same.

Also for many of us (at least on FT) that have so many CCs in our portfolio, it becomes a question of what is the differentiated value to each card. The issue with the CSR is that the only features it has that differ from my other "premium" cards is primary car rental insurance, and favorable earnings on travel and dining. I don't really care much about CSR's Priority Pass because I have it through other cards and virtually never have a guest. Since I max out the $300 travel credit with organic spend, I consider it a $150 AF card where I just happen to prepay $300 in travel expenses. If I didn't have to keep at least 1 AF paying card to unlock the value of my UR points that would probably also give me less reason to keep the CSR.
