but... how is that compatible with the article I linked here? Some galaxies look like they have very little dark matter, a MOND with no free parameters can't explain why different galaxies have different inconsistencies in their rotation curves.

You actually have to do the math, it's not just a "no dark matter hurr durr" thing.

MOND predicts "no dark matter" if the acceleration regime is high. Most galaxies that havd "very little dark matter" are in the high acceleration regime.

Most of the others seem to be susceptible to observational error (e.g. ultra diffuses). Galaxy rotation curves measurements are highly sensitive to orientation of the rotational axis and distance to us (you're gonna have a hard time measuring it if the galaxy is face on)

Correct. MOND cannot explain why some galaxies don't fit it's predicted rotation curve.

However, the vast majority do, and the linked paper says that the ones they are describing are extremely rare.
