'He has learned nothing,' Zuckerberg considers crowdsourcing news fact-checks for Facebook

[L0ki]

@Snork

Breaches of trust? You mean news about companies losing personal data? That has absolutely nothing to do with vaccination, or global warming, or other things. And people should not distrust experts on matters like that because of nonrelated matters, but they do. That’s the problem - people conflating things that are not even in the same ballpark.

I would guess @HMSGoose is thinking more of things like:

Andrew Wakefield - Wikipedia

or

C. C. Little

to name but two.
