I don't agree with Eliezer on everything, and I often find him obnoxious personally, but being obnoxious isn't the same as being wrong. In general I think it's worth listening to people you disagree with and picking out the good parts of what they have to say.
In any case, the broader point is that there are a lot of people concerned with AI risk who don't have a financial stake in Big AI. The vast majority of people posting on https://www.alignmentforum.org/ are not Eliezer, and most of them don't work for Big AI either. Lots of them disagree with Eliezer too.
