Google was pretty much considered the "good guys" back then. It only started with AdWords a year earlier and was barely breaking even at the time. Loong way from "corporate overlords".
It certainly smacks of being someone's promo project where they moved on to other things after the migration and the project fizzled out without leadership.
So Google came in and saved it.
