You seem to be latching on to individual sentences in individual posts rather than understanding the thread from my initial post downwards. Start from the top and see if that changes.
Right from the beginning I was walking about people not releasing source for this reason, not releasing with expectations of control – while quoting more of the preceding thread might have made that sentence look less like an attempt to hide as you see it, that would bulk out the thread necessarily IMO (and I'm already being too wordy) given that the context is already readily available nearby (as the thread is hardly a long one).
