Because of dithering, that photo is 50kB, jpeg could easily have the same size and look much better.

Exactly. Dithering creates a lot of noise and PNG is poor choice to compress that.

it's the opposite way round. png is especially good at compressing dithered images.
It's a reduced color palette, (in this case just black and white) so there's lots of repeated sequences. Which works very well with lossless compression.

And yet, a 50kb JPG would look much better.
