There are multiple companies on my blacklist that definitely got me to sign up. But as there was a hook that anybody acting as a trustworthy partner would have mentioned, I parted with them — potentially for life. You know, things like "click here to sign up, sacrifice your newborn on a fullmoon night while reciting the last 3 digits of pi to cancel"

I don't particular care whether their A/B test captures that potential aspect of customer (dis)satisfaction, but I am not sure how it would.
