Quasars are just active galactic nuclei with an absolute magnitude of less than -23 or something pretty arbitrary. I made this page to investigate the data (select DR16Q):

They have a lower magnitude (meaning brighter) in the past than today.

Whenever we scrutinize that data, we usually find they are a double quasar, have intermingling starlight, or are lensed.*

We should be highly suspicious that the brightest ones are actually that bright. Of the 750,000 quasars in the catalog, less than 7000 have abs mag < -28. This selection of the data is largely what their conclusions are based on.

... in addition all quasar spectra show a Lyman-alpha forest, which means that their light has traveled trough a lot of hydrogen gas that amplifies the redshift. The large distance and apparent luminosity of quasars is an illusion, quasars are a lot closer than the distance implied by their redshift. The study cited above is worthless.

When I made this post, I think I did so because it seemingly confirmed some mainstream theories about why mature, red galaxies were showing up in the early universe.
