No offense, but yes it is. Aureate is one of the oldest spyware companies. Cydoor is one of the worst. Gator is a new one, but it's also rather infamous of late. Ezula is the least of them, but it and Gator are not only spyware, they are thiefware in that they steal from the users and they steal from webmasters by changing the content of their site and in Gator's case it replaces paid-ads with those of the Gator's clients.
Cydoor installs even if you tell it no during the install. This is established. It has been tested over and over in every version of it. It remains behind (as do all of them) even if you attempt to uninstall them and the host (limewire). It sends back information about the user's habits (as do all of them). That is the definition of spyware.
Make up your own mind. The best information about them can be found at this site, and I say that as the owner of another spyware site.
