Seriously? You expect us to believe you maliciously hijacked user's search results and put in your own affiliate links just because you thought it would be "nice"??

>In the spirit of transparency

AKA "Now that we got caught acting against the spirit of transparency..."

>we should disclose that this feature does bring small amount of revenue to us

Yeah, no shit; but someone else already "disclosed" that.

>Since so many users don't like it, we already updated a new version(3.2.1) to remove this feature.

So what? You've demonstrated a lack of respect for the user's trust and privacy. Why should we trust a liar?
