I disagree with that sentiment. The members and moderators of Winamp Forums volunteer their time to provide tech support. If we thought that Winamp was turning into adware, many of us would not be here.
You are given the option not to install the Emusic offer in the install options
. Also, you are give a uninstall icon in the 'Add & Remove Programs'.
Many adware programs are surreptitious in manner and can also be malicious. Many adware programs don't give you an option not install ad part. Many adware programs integrate the ad part in to the core of the program or "hide" in such a way that it very difficult to get rid of. That is not the case with Winamp.
