Can you provide some evidence for that claim? I know that perfluoro compounds degrade very slowly and accumulate in fatty tissue, but I haven't seen a supported claim about harmful effects. From the misleading links in the article, I suspect more than a few people confuse PFAS and PCBs.

It's not too surprising if the effects sound similar to PCB effects. Both are associated with aryl hydrocarbon receptor activation.

Here's a study of thyroid hormone effects in rat cells:
