I agree. Google could have easily turned Allo into something very similar to iMessage by just adding Google account support, default E2E encryption and SMS fallback. It would have also worked on every device that was connected to the Internet. But, it looks like they've decided to get into bed with the carriers again and used some altruistic bullshit explanation that an open solution, involving the carriers, is the right solution. This company just can't seem to learn from its mistakes.
