It is not too surprising that many HTML or JS based watermarking schemes are very easy to remove, some even via a script. For watermarking schemes to be effective, the watermark payload needs to be embedded in the content. Here's one approach that works for images:

Incidentally, the latter also supports applying the watermark payload to HLS segments.

If you're obfuscating code or writing anti-debugging logic, you are the bad guy. Stop trying to control other people's computers.

On reading the title, my mind went to crafting image (or video) uploads that effectively “undo“ the water marking. That is, is there a way to alter content before uploading it so that when the watermark is applied it reverts the change and so what is displayed lacks the watermark. That would be crafty.

You could, but then it becomes even easier to capture without the adornment, practically defeating the purpose.
You may be interested in watermarks that are invisible to the human eye but are visible to spectral analysis. You can even encode data within this invisible watermark, and learn a modification that is resistant to various image manipulations and even resistant to lossy compressions, in research that goes back to 2001 and has seen interesting improvements with advances in DNNs, Transformers and Diffusion.

It's a good article, but I was a little disappointed that he only went over crude watermarking technologies. The more advanced systems implant an invisible watermark in the image or video itself by using neural networks. Those are a lot more tricky to bypass than simply removing a floating div.

To be honest if you are doing client side watermarking outside of a secure hardware enclave I'm not sure you expect any genuine robustness, because you obviously don't have any.

Bypassing of different Watermark implementations; including tricks related to Picture-In-Picture, erroneous assumptions at the time of enforcing client-side protections, and then HLS (HTTP Live Streaming) and ways to reassemble videos offline by looking into m3u8 playlists and encrypted video segments.
