Yes they have (escaped) and yes they've stopped later WHDload releases working with them. WinUAE might even purposefully crash with older pirate keyfiles and WHDload, but can't confirm that as 100% true.
Registering WHDload isn't much to ask, inexpensive and a one time commitment yet works freely for those who can't or won't so the current system works well.
