There is an application called NeoAudio, which is a straight CDex rip off. They changed some string (i.e. replace CDex with NeoAudio), changed the logo and added some nice SpyWare and Adware. I contacted Richard M. Stallman about this issue, but unfortunately I can not do much about it, except for the fact that they are removing/changing copyright strings which they should not. So please do not download and install NeoAudio (they probably make quite a few dollars by shipping the adware) and also advice other people NOT to download NeoAudio either, and warn innocent users not to download this application but download CDex instead.
There are always people trying to exploit the good will of people like the open source developer. Spread the word so that this leach will get minimum benefit from the trick he has pulled.
