There might be a lot more non-malicious people in the population as a whole but I would not be surprised if there are more malicious than non-malicious people in positions of power, including those positions where you can make anti-competitive decisions for a giant megacorporation.
But even if that is not the case and malicious people are not the norm even there, using Hanlon's razor to try and shut down any discussion of possible malicious actions still ends up empowering the malicious actors that do exist. It's a decent rule for first interactions with human people that you don't know better but is absolutely not the right tool for corporate entities who can much more easily brush off any consequences for being caught acting maliciously. It is outright stupid to apply it to corporations that have a history of maliciousness.
