Please Mr Airbus...do something about a system that will trim against a pilot in the case of partial or substantial upset.
Airbus auto trims with pilots inputs not against. If the automatics degrade then it leaves the trim as is. As far as I have read FAC never trims against pilots inputs. If you try and confuse auto trim by "whisk the mayo" then it will average the inputs. The problem with recent event appears to be recognizing when auto trim is on/off and not following procedures. When pilot takes control he/she needs to check all flight controls - there aren't that many - should take but a couple of seconds!
