Honestly, I didn’t read their comment as taking any sides; it’s really just descriptive of their perspective. There are good arguments for why this is fraud in a particular way and another commenter in this thread pointed out (correctly, in my opinion) that “overbooking” is a similar kind of fraud on the airlines’ part.

Point being, many happenings are more nuanced than Alice wronged Bob and Bob did nothing wrong to Alice. I suspect if you read the parent comment again you may indeed find some of their points to be agreeable.
