I definitely seen him cited as an authority by AI critics far more than anyone else. The bending truth to tell them what they want to hear (and the gratuitous swearing) really helps.
Per number of words in article possibly. But I do not think he "sucks air out of other critics".
I mostly assume that most people end reading his articles somewhere in first third and go on reading something easier to read. His articles are not exactly casual read material and they are loooong. You have to have certain kind of personality to get over first few paragraphs.
Claiming that a single journalist blog has power to stop others from criticiaing ai for different reasons ia kind of absurd.
