I don't think you can make the absolute statement that there is no audience or market for these tools. I enjoyed watching all of these videos. They are far from banal crap. They are deranged. They are not intentionally deranged, it is limitation of the tool. If a video artist were to employ these tools not to save effort, but instead to create an aesthetic it would be proper and good use. Just like non-AI video editors or color grading tools.
