[Harry Potter] How did the Ministry of Magic present their abrupt policy pivot to the public when Voldemort took over?

At the beginning of Deathly Hallows, the Ministry has been infiltrated but is still officially working against Voldemort and his cronies. For example, the Dept of Magical Transportation makes it illegal to utilize several forms of magical transport near the Dursley's house, ostensibly for Harry's protection (but, in actuality, this is because they've been infiltrated and wish to ensure Harry cannot leave undetected).

However, within a few weeks, the former Minister of Magic is killed, and the new Minister of Magic is under Voldemort's control. Almost immediately, the Ministry's policy shifts from *"protect yourself from death eater attacks"* to *"Harry Potter is Undesirable #1"* and oppressing muggle-born wizards.

My question is, how was this abrupt policy 180 sold to the public?

It was an open secret. Anyone who questioned it too strongly would be labelled a muggle sympathiser. So most people just went along with it, because there was no way they could overthrow it. They couldn't band together, because just like in the last wizarding war, it was impossible to know who you could trust.
