That article is about DRAM, not NAND. Any article that talks about SK Hynix as a major player but doesn't mention Toshiba is clearly not about flash memory.

Ah yes, my bad. The lawsuit in that article is indeed specifically about DRAM. A lot of the reporting on this mixes them up for some reason. But the DRAM and NAND industries are largely the same companies and both have been under investigation for price fixing recently.

The DRAM and NAND markets are similar, but there are important differences. The NAND market has several more major players and is significantly more competitive.

And the Chinese accusations of price fixing need to be understood in the context that they're trying very hard to get their own NAND fabs up and running, almost certainly using at least some stolen tech. Even without Chinese influence, NAND prices have fallen dramatically since that article was written, due to ordinary healthy market forces.

Sandisk and Toshiba have been investigated for price fixing.

What a weird article. The latest brouhaha is about memory, not storage. The website shows a NAND SSD though as the main picture... strange... and incorrect.
