I'll say here what I said on the Bugzilla feature request to have a version of Firefox without this malware pre-installed. Namely, as a user of Firefox I expect the browser to behave more or less in my best interests, at most times, and in most ways....
I'm old enough to remember when that was called "machine learning," and wasn't doing the branding work for giant companies that do not have the Internet's best interests at heart.
