When I first read the thread title "Don't bite that hand that feeds you Calibre", I read it as a warning to Calibre not to bite the hand that feeds it. Ambiguity, the devil's volleyball.
After reading the thread, ofc, I was reminded that it's been FAR too long since I last put my hand out to feed Calibre, so have now taken action to fix that, to a tiny degree. Thanks, Kovid!
