Exactly my thoughts. It is a crystal-clear admission that this is a bit of irritating badgering for the benefit of a beancounter at BA and not the passnger.
Since BA have yet to send me a useful SMS, I think perhaps I should "change" my mobile phone number, although the only times I don't OLCI are when it isn't working or (more rarely) I can't get to a computer easily; so I might escape this particular service disenhancment although if I don't it will make their hectoring all the more annoying.
