Earlier quoted context omitted.
I assume they're trying to break the inertia people have with major banks. There's no reason to change bank unless there's some substantial incentive like favorable interest rate to offset the hassle involved. I'm not sure there's an ulterior motive here other than customer acquisition.
Right, but that incentive is only substantial if you’re going to park a lot of money there, which is exactly the sort of customer they don’t want according to the comment I replied to.
You are assuming that customers make this decision rationally; marketing very often leverages the fact that humans very often don't do that.
