The main constituency of the Conservative Party is old people that want their pensions to be increased, house prices to go up and the kids to stop having fun, whatever the cost.
When their idiocy demands something that would cause the utter destruction of civilization as we know it (such as banning encryption) they back off. If it makes it harder for the old person to access porn, they back off. But when the consequences won’t manifest themselves before 2-3 years, they go ahead and then blame the EU or the Albanians. Let me know if they have chickenpox vaccines, Zoely (the contraceptive pill) and lactose free milk in your area. My stockpile of Calpol should be enough to survive the current shortage.
