As someone who is currently studying dark matter, MOND is currently disfavored in the field of cosmology. It does not as simply or effectively describe galaxies closer to home, or observations of the cosmic microwave background. These galaxies pose a challenge to lambda-CDM, but that does not prove MOND correct.
As someone who watches a lot of PBS Space Time and Dr. Becky, I'm always very suspicious of any news article claiming '"JWST has found evidence for X", especially if it's an alternative to Lambda CDM
