The problem that has caused the moderators to be rather sensitive about ATM in Q&A is that asking an apparently innocent question fully intending to later turn the discussion to their pet idea has been a favorite tactic for ATM proponents who are really pushing their agenda.
It has abated somewhat after several people got permanently banned for doing so, but the lingering effect is a heightened sensitivity for, and stronger response towards, threads that begin to stray.
It's a case of once burned, twice shy.
