From the link:
The lawsuits were filed on behalf of owners of General Motors vehicles, which were factory-filled with "Dex-Cool" coolant. In summary, the lawsuits alleged that Dex-Cool degraded certain vehicles’ intake manifold gaskets and other engine sealability components, and that in certain other vehicles, Dex-Cool formed a rusty sludge, clogging the vehicles’ cooling systems and causing vehicles to overheat.

Fascinating. The radiator in my 01 was clogged with rusty sludge. But according to IMMEGT, I am obviously wrong. I stand corrected.
