There isn't much money to be derived from the product (as is) and it takes a small team of people to focus on it in order to maintain it. Someone with at least a modicum of influence has to care about the product and drive resources at it persistently so it doesn't rot. Google is unlikely to want to go further and build or acquire a stock broker business, so they're going to struggle to extract much money out of the category over time. This is Google doing the bare minimum as an alternative to just shutting down another product. I'm surprised it has survived this long.
