I thought modern freezers were meant to have better insulation, so why is
mine always running?

Something has died, either the thermostat or what
reads it or the connection between them most likely.
Or the refrigerant has leaked out.

It doesn't seem to have a lower duty cycle than the old ones of 30 years
ago.

The duty cycle doesn't necessarily change with the better insulation.

Sure, the power consumption (according to the label) is less, but
shouldn't they have better insulation nowadays?

Yes, and they do.

Or was all that banned by the greenies for that ozone nonsense?

Nope, in fact they demanded better insulation.
