Provides a somewhat interesting look into what Google wants out of Google voice. I think it’s really only interesting because traditionally phone calls have been much more protected than other types of communication. Otherwise, Google has tons of different products which don’t seem to make sense from any traditional “how does this make money” sense.
Still, it does beg the question of whether I’m giving up any protections by using Google voice rather than just using a normal phone line.
