I work in the state government space. Many targets/victims of ransomware are small/local government agencies and the ransom demands are greater than their annual budgets. Not every agency is big enough to have someone (bored) come in on Sunday, notice stuff getting encrypted and then run in to the server room and hit the big red button like Virginia's legislature in 2021[0].
Many ransoms are far more than the victim can actually pay. Not all ransom payments result in a decryption key that actually works.

Most local governments lack the scale and budget to competently maintain their own IT infrastructure. It's not just security but everything. They should outsource the infrastructure layer to a large contractor, or possibly to the state government.
