The problem is when it writes things that have the appearance of making sense but actually don't, when it writes what could be better put in 10% of the words, when it writes with no coherent logic. I don't have the time or the mental energy to wade through that on the faint chance that there might be a gem in there somewhere. But I have the same objection to human writers who do the same things.
Write something worth reading. I don't have time for it otherwise.
