Yes, the bullet cluster effectively disproves most theories like MOND and similar. This article doesn't mention the bullet cluster. The article is dead on arrival as far as I'm concerned.

There's not a very good path forward for MOND-like theories with regards to explaining these galaxies. https://en.wikipedia.org/wiki/Ultra_diffuse_galaxy https://en.wikipedia.org/wiki/Ultra_diffuse_galaxy
