There's obviously a difference between the broad understanding OP is talking about, and the low-level physics that goes into a computer.

Also, one could say that there's a stark difference between saying people who do not understand how misinformation works on a platform should not use that platform, and for example saying people who don't understand toasters shouldn't use toasters.

For the record, I don't understand the low level physics of toasters. As far as I know, they're magic bagel browning devices.

A toaster has fairly benign failure modes, so this strawman isn't really a reasonable one. Though I hope you understand toasters enough not to trigger your smoke alarm every time.
