It's a tool. Tools can be used for good or ill. This tool is the hotness right now so it's quite overused in a lot of poorly fitting situations. This particular usage serves no socially beneficial purpose and needs to be regulated into non-existence (we at least shouldn't pay people to do it). The tool is still useful for a bunch of things but some people get irrationally defensive if you critique their favorite tool. It's a good tool and it's a flawed tool - like every other tool.
In your opinion, what is the positive aspect of this kind of AI video/voice generation tool that these videos are using?
In my opinion, AI video/voice generation is being used to scam and manipulate people en masse, without a compelling, good use case besides generating more (slop) content.
When someone uses AI to make a video, they either have nefarious purposes (such as scamming) in mind or they don't. That's not a matter of your opinion. It's not hard to picture someone making a video with innocuous intent to inform or entertain and using AI in the process does not suddenly make their intention a malicious one.
