Except that the list isn't configurable, it doesn't obey a schedule, doesn't work on a timer, doesn't serve up the cutesy quotes, and this entire method is unsuitable for most users. I agree that the app in question is quite pricey for what it does, but to claim it's literally no more than a few entries in /etc/hosts is severely undervaluing the obvious effort that's gone into packaging that core concept up into a user-friendly whole.
