I see, so whenever anybody states their position tersely, I can accuse them of using a motte-and-bailey argument, and force them to be so pedantic and long winded that their point get lost in the weeds. Unless I like what they're saying, of course. I'll keep it in mind!
The author has a narrow defensible point (OpenAI and Anthropic have questionable business models) and rather than stating it tersely, he’s instead tried to use that to write an unfocused article dismissing all of Generative AI as a con.
It feels like you neither read the original article very carefully, nor took the time to understand what a motte-and-bailey argument is before writing this.
