The lesson we should learn from this is that the tech industry needs a regulator. Anyone selling software that runs with root privileges should be required by law to adhere to a testing standard, especially if that software auto updates. The rest of the economy should be provided with resiliency and redundancy guidance from said regulator.
@rlamacraft Uh, no, the lesson is that we shouldn't have such a concentrated market. No one vendor should cover so much of the market at any given time.
