"but the general goals were to ensure all data was encrypted and no government would get access to it."
Kind of, but not quite.
Little known history: BlackBerry 'became encrypted' because back in the days when it was really just a 'pager with email' - North American carriers (channel partners) were actually reading BB executives emails during negotiations (!!!). BB discovered this and decided to start with the encryption. Seriously - the first 'illegal' act was by BB customers/channel partners!
From there, it was always pragmatic. BB was never specifically motivated by protecting individuals from governments persey.
