He’s not a member of the media. Not in any credible way, anyway. The answer to the question is none of his business.
Well, his media outlet is really crappy, easily one of the crappiest in Canada, but that doesn't mean he's not a member of the media if we happen to disagree with his media coverage. Our Charter rights, freedom of the press et al, do not depend on whether we like a person or not. TMZ is media too.
He has a right to ask Omar a question just like media can go to a courthouse and put a mic and camera near a person's face, and Omar has the right not to answer, as he did. If we're going to defend Omar's rights, as we should, we should defend Ezra's too.
I don't enjoy defending the guy, but he does get unjustly bullied/censored by police/authorities because of his political leanings (note, he's a lawyer):
