Hi, author here.
No. Fortunately, they don't make Ask toolbar for Ubuntu. ;-)
My point is Amazon is using deceptive practices to push Amazon Prime - which are actually very similar to to the strategy employed by crapware like the Ask toolbar. You just don't expect that when you're making a purchase over amazon. Well at least I never would, until now.
Are you really telling me you think it's okay for Amazon to do that - and there's no reason to complain here?
