What will restore confidence is legally punishing people who deliberately hide information about the safety of their devices.
What will restore confidence is published data that suggests progressive reduction in the amount and number of device malfunctions.
What will eventually restore confidence is sound engineering and medicine practices.
Not word - play.

Yes word play is sometimes child's play.
