It's natural to believe stories that suit your agenda .It certainly is, as was illustrated by all of those who believed every word that Cummings and Johnson said, pre Brexit vote, however ludicrous some of it was.
I agree with those of you (Dickens, WWMk2) who are pointing out that this is the tip of a very nasty iceberg, sent out by some very nasty people. Smiling, smart Sunak is heading a softly softly campaign, and this country wont know what has hit it when his austerity campaign hits. People still believe that covid19 'has to be paid for', and they generally prefer it to be paid by the undeserving 'benefit scroungers', bogus asylum seekers and other groups as they are instructed by the right wing press.
But, back to the OP, Cummings is a liar, but a liar with a mission, a mission that we should all be very frightened about. It is obvious that the farce in the Rose Garden was orchestrated to demonstrate to his real paymasters that Cummings had a hold over Johnson. Be afraid, be very afraid. You will not be allowed to demonstrate your displeasure, and for some groups of the electorate, will not even be able to show your displeasure or support through the ballot box, but that, as has been discussed on GN before, really doesn't bother anyone. I could weep. Oh, and anyone who thinks the BBC is left biased in its reporting isn't watching the same BBC as I am.
