Zango's in your Face(book)

The Zangonistas are at it again, this time deftly disguising their "software" as a Facebook Widget. Fortinet, who discovered the issue, discusses the "Secret Crush" widget at length, so no need to repeat their extensive effort.
Instead, I'd like to offer a bit of analysis, then invoke a debate.

ANALYSIS

I ran Setup.exe, as found in hxxp://static.zangocash.com/Setup/46/Zango/Setup.exe, through the analysis mill and I think the evidence speaks for itself.

Wait a minute...I haven't accepted the EULA yet!
Let's discuss.

DEBATE

You know my opinion, I think Zango's offerings are spyware, I always have and I always will. They'd prefer their products be referred to as adware and that they're harmless. I have debated this issue with them in person (perfectly nice people, but analysis supplants personality), and they would argue that, because their software only installs with the explicit consent of the enduser, it can't be labeled as spyware. To which I say, if it calls home, reports behavior, and shapes a response based on said behavior, it's spyware, EULA or not. Round and round we go, where we stop, no one knows. The searches define:spyware and define:adware will provide impetus for the debate.
If a user knowingly installs a widget or a piece of software with a EULA that describes it behavior, can it objectively be called spyware or malicious?
Comments welcome. Cheers.
