I don't doubt that Peterson is an excellent psychiatrist. But one can be quite talented in one domain and totally out of one's depth in another.

I have a lot of beefs with Peterson, many of which I've written about, and which you can read here:

Olivia Wilde's point, and I think it's a fair one, is that whatever you might think of Peterson, he has clearly developed quite a following among a number of very online groups associated with the alt-right, including neo-reactionaries and incels.

It's useful to ask why that is. Peterson's misuse of evolutionary psychology in the service of defending social hierarchies and traditional religion is one reason. His obsession with "postmodern cultural Marxism" (which is a contradiction in terms, btw) is another.

As I said, a good psychiatrist, sure, but not much of a philosopher, whose main purpose these days seems to be to give a veneer of respectability to right wing trolls.
