One of the videos turned out to be a fraud. That does not invalidate any of the others. It's like how lots of people immediately assumed LK-99 was a fraud because Ranga Dias' high-pressure room-temperature superconductor was in the process of being retracted due to apparent data manipulation - they're completely unconnected things.
If 99 labs fail to reproduce LK-99's superconductivity, release fraudulent videos and data, and so forth, but one lab is able to perfectly reproduce it and show that it works, that lab wins and LK-99 really is a superconductor. Scientific reality is not subject to democracy.
