I think he’s just kinda an ordinary person who grew up privileged. He has fairly standard techbro style libertarian beliefs, but he also has criticisms of some of the influencers he watches, and didn’t seem to like Peterson very much. He also seems to be an environmentalist, and I think he seemed to have become more anti-corporation based on the manifesto released (obviously assuming he did it).
Him being a privileged but ordinary guy who still got radicalized reflects a lot more strongly on the plight of everyone who isn’t one of the owner class. It doesn’t matter that he was relatively wealthy, he still wasn’t one of them.
Saying the crime was “broadly condemned” in the same article about the flood of money and support he’s received, with a large section of said article being about the praise given online, is an interesting way to frame things.
