The controversy was also noted in 1999 by Chemical and Engineering News (repeated without additional content in 2004), and in 2000, the World Association of Theoretically Oriented Chemists Scientific Board held a referendum of its executive board members on this issue with a majority (23 of 28) approving the resolution opposing the restrictive licenses. These assertions were repeated by Jim Giles in 2004 in Nature. The anonymous group has published a list of scientists whom it claims are not permitted to use GAUSSIAN software. Some scientists consider these terms overly restrictive. has attracted controversy for its licensing terms that stipulate that researchers who develop competing software packages are not permitted to use the software.

These were unofficial, unverified ports of the program to other computer platforms. Other programs named 'Gaussian XX' were placed among the holdings of the Quantum Chemistry Program Exchange.
