They call them electronic transformers and the 'proper' transformers
toroidal - which is actually a type of transformer. I've seen low
voltage lighting true transformers which weren't toroidal.

But it makes some sense to call them all transformers because they do
the same job. And most won't be interested in any differences
internally.

True, but many will not realise that much of the control circuitry of an
SMPS is at mains potential, so represents an unexpected hazard.
