Why with you does everything have to be black and white? No middle ground. No shades of grey.
There is absolutely nothing wrong with saying that the UK and other nations such as France and Denmark should be following the guidance of Pfizer and going with 3 weeks of spacing.
There is also however nothing wrong with saying the logic - which has been explained by the CMOs - is reasoned in why they are extending or have extended the spacing. It is, as Whitty put it "a calculated risk" - but at this stage, the entire world is having to take a calculated risk or we'll be stuck in this cycle forever. People bang on about Aus and NZ's success - and it is success in dealing with this - but they are placing entire regions into quarantine for even one case. That is in no sense 'normality' and it is in no sense sustainable. Countries relying on Pfizer right now are taking a risk because they can't get as many doses to people as quickly as they'd like, so there's still going to be a risk of the virus spreading through the population, and continuing to mutate that way.
It is also fair to say that there has been plenty of warnings against the extended spacing on Pfizer. And it is also fair to say that so far, there is no evidence of it not working to the effect that those warnings claim.
People do care. They just can see things from different perspectives and don't automatically assume that people are evil or don't care, but are doing something to try and see if it's going to help us out of this quicker. It might backfire spectacularly, but so far it hasn't. Let's hope it doesn't and the risk pays off. Not because of some race to be first, but because it'd save lives and ultimately get the virus suppressed quicker because more people would have that initial protection from falling seriously ill from this, and that stops the NHS being overrun.
Ideally, if they're going to keep doing this for now, then I'd like to see, once we have the Moderna vaccines on order and the AZ continues to ramp up, and then J&J and Novavax (which there is 60m of secured) come along in a few months, the spacing reduced back down to less time. That would also coincide with the summer months and easing of restrictions so would definitely make sense.
But back to the initial point, people do care, they just understand reasons why sometimes, you have to take risks. If there is one country in the world that absolutely needed to take a risk to try and get vaccines out to as many people as possible, then it was the UK. There's no easy solution.
