This is overstated.

In the old days, there was a hierarchy of reputability. At the top you had the bluechecks that generally represented reputable sources of information, who had premium billing in the platform. Then you had the normies. Then you had the slush-pit of soft-blocked people that were shoved into the "other replies" box because everybody hated them and they only followed their network of bots.

Now, the hierarchy is reversed. The slush-pit people are now have blue-checks, the algorithmic boost on blue-checks is even stronger, and half of the old reputable blue-checks have left.

This is like saying "Reddit/Lemmy has always been awful" if we made the upvotes/downvotes of all the worst people on the site worth 100X what a normal person's upvote/downvote was worth. Yes, there have always been problems, but they can get worse.
