We need to see the actual data to conclude either way. It's so easy to make a statement like that which sounds compelling but conveniently hides some nastiness somewhere else. Just as it is so easy for the whistleblower to cherry pick a stat to make her point. Neither of them are lying but their framing may have some level of dishonesty which is obscured from us since we can't look at the bigger picture. We have no idea how these questions were asked, the methodology, etc.

Anyway, there's lots of research on social media done in universities, so we don't need to take their word for it.
