All 3 points come down to one basically: We, as people, have accepted piss-poor security in so many computer applications for years, but now we have put important stuff within an electronic arm's reach of world+dog to have a go if they feel like it.
The current arguments about cryptography for law enforcement, etc, is a stupid distraction flamed by clueless politicians and civil servants and distracts from the above. We have found ways of catching and prosecuting criminals when they talked in person and did not write stuff down for many many years, so while it might be nice to get phone contents, it should not be necessary.
Sadly we need to start making a big deal about businesses and gov departments that expose important stuff (from personnel/medical records, through to infrastructure like power and gas) to the world, and/or collect sensitive stuff they don't really need. Make damn sure that those in charge can face personal prosecution if they fail to manage the process, fail to have a system in place to check and fix things, and fail to get outside support to check its good enough.
