I'm not morally/philosophically opposed to someone generating text with AI. I just don't want to read something that isn't really "owned" by the person creating it (that is, the writer knows what he is sending me and endorses all of its contents), and because I can't discern that from people I don't know, I tend to view it with suspicion by default.

This is perfectly valid position to have. I also feel the same way.

Unless I'm directly interacting with the LLM, someone should endorse the content.
