ACS move for NIH's PubChem

According to govdoc-L:
"The American Chemical Society is calling on Congress to shut down the NIH's PubChem, a freely accessible database on small organic molecules. PubChem is an important component of NIH's Molecular Libraries Initiative, which is a key element of the NIH "road map" for medical research. ACS claims that PubChem competes with Chemical Abstracts Service (CAS). In reality, PubChem and the Chemical Abstracts Service databases are complementary, not duplicative."

How many public domain databases are being moved to the private sector? It started with PubScience, ERIC, and now PubChem???
