Ironically having a giant security breach happen in a security focused messaging app was good advertising.

Of course in this instance the breach was not because of the app, which is a good thing I guess.

Agreed. Get them a ChromeOS device, or get a good refurb business class laptop and put ChromeOS flex on it.

Yes it’s not what OP is probably wanting, but this gives them a device that is hard to mess up with a minimum of training.
