The difference between Cummings and somebody like Emma Thompson is that Cummings has (and still has) a huge influence over the Prime Minister and policy which directly affects all of us. We can disapprove of Emma Thompson (and some others) but what they do doesn't really affect us. Cummings is more than a role model. He's an influencer.
Cummings has been attending Sage meetings. Nobody really knows how or whether he's influenced any decisions made within the meetings, but it clearly undermines any claim that scientific is politically neutral. The brother of a friend of Cummings was given the contract and paid £250,000 to develop the NHS app, which has been fraught with difficulties. His history is an indication that he has his own agenda and makes a nonsense of the idea of independent MPs, answerable to the electorate.
Cummings' wife wrote an article and did an interview, which failed completely to mention the family wasn't at home in London when infected or that Cummings' parents were involved in caring for their child. I've read that interview many times and it gives the opposite impression. There is a very strong suggestion of a cover up.
This is hypocrisy at its very most blatant.
