Just a few years ago, paramedics in Germany were routinely (and probably not entirely legally) using WhatsApp for communicating with the hospital while en route because there wasn't (and still isn't) a reliable, secure and interoperable system allowing healthcare providers to communicate with each other.

It's not like people in Germany are using tools such as WhatsApp in a professional context because they're negligent or careless (at least not entirely). Often, the digital infrastructure available to them is so woefully inadequate they have to resort to non-official tools.
