Yes, I seem to recall reading it had been downloaded 10,000,000 times.

Looking on the positive side, they are still providing CWShredder free?

Being the sort of guy that I am, I visited their site and looked at the licence agreement . Down in the small print it says for "personal use" so maybe they intend to bundle it with their corporate security suite and charge for supporting that?

I can also believe their suggestion that it is for them to gather data on malware trends. Corporates tend to keep attacks and infections quiet, whereas private users generally just want it fixed.
