What would be an explanation for the partial levitation of the LK-99 sample shown in the video?

Could be normal diamagnetism, or even ferromagnetism. Very hard to say as they don't even give any field strengths in the video, it's just a Neodym magnet they hold near the sample. If I understand the video correctly they just orient the magnet by hand, so I would not even rule out a ferromagnetic effect. There can be multiple regions with different orientation in such a polycristalline material, which can produce a…

Have you seen the flux pinning video released recently (within the last 24 hours) - https://www.tomshardware.com/news/superconductor-levitates-a... - does it change your opinion?

I don't understand why she would be like this. Why would anyone hold back the production process for a material that could change humanity forever?

It takes a lot of cognitive dissonance to be pro USSR in the first place, so a little more shouldn't hurt.

USSR means something different to Russians than it does to Americans. To Americans it was the Enemy. To Russians it was the last time that Russia was truly important on the world stage and had some degree of prosperity.

To Russians that had at least a couple of brain cells it was also the enemy.
