I joined PFA quite a few years ago because I thought I should support such a body on principle (I don't fly a PFA-type aircraft).
About a year ago, I got a letter from a departing senior person to tell me that something is rotten in the state of PFA. Soon after that, I heard that senior PFA engineering folks had been fired and worse (but not why). That worried me - do I want to be a member of an organisation that treats people like that and doesn't explain itself?
Recently I was told of a rumour that if I fly a PFA aircraft as a "co-owner" I will in future be obliged to be a member of PFA, whether I want to or not. Postings on here indicated that it's true.
Then I saw the charges for going to the PFA Rally.
Last month I cancelled my standing order. I did so very sadly, but enough's enough. The same principle that led me to join, led me to leave.
