Show HN: I made an OSS tool to remove Sora 2 Watermark in less than 72h released

https://github.com/Kuberwastaken/sweeta

being on platforms like Instagram and Twitter for the past few days, I've noticed how many non-technical and mostly old people just assume the video is real despite the watermark Sora 2 generations have.

Think what would happen if there was no watermark? This is the reason that this project exists. It's not to abuse the great initiative by OpenAI to put logos onto every generation (though temporarily there's also an easy way to bypass that which I wouldn't cover), it's to hopefully encourage them to be harsher and more obvious with it in some form.

Sweeta is an AI-powered watermark removal tool specifically designed for SORA 2 video generations. It Uses advanced inpainting models (LaMA) and intelligent detection algorithms, it can seamlessly remove watermarks while (mostly) preserving the original image quality.

Everything would be worse and lies would be even easier to propagate. I understand the point in building this—understanding if it is possible—but what’s then the point in releasing it with instructions?

It’s like inventing a new kind of undetectable poison and saying “Could you imagine what would happen if people put this is in each other’s drinks?! Anyway, here’s the recipe”.

This means absolutely nothing. Absolutely no one, exactly zero people in the history of mankind who have unethical uses for this tool will care about the message.

What even is the responsible and ethical use for your tool? Is there any?

Consider that you can’t push ethics down the line, they have to start with you. Should you have shared this? Is that ethical? Again, I understand the building of it, especially to demonstrate to OpenAI their efforts to prevent deliberate misuse (assuming that’s indeed the goal of the watermark) are laughably inadequate, but should you be distributing it to every random petty phisher and scammer on the internet?
