I'm guessing they had to update this FAQ after they started ignoring the OP (and other customers) messages. Also, something is wrong with the timeline with regards to the OP's blogpost where they say they've been using Firebase for a while.

Yeah OP says they've been using FB with similar costs for over two years, so I highly doubt they're complaining about something that was only a problem for the last 6 months.
