Anthropic has said they don't know if LLMs could be conscious.
Ted Chiang has said they are definitely are not conscious.
Nothing spreads the idea that "X could be true", better than the putting forward of controversial argument that "X is not true".
This is an absurd take if you know anything about Ted Chiang and his previous writings, both fictional and non-fiction. He is most definitely not intentionally marketing for Anthropic. In fact, he hints these are marketing tactics by Anthropic, and they don't believe their own hype.
