This is certainly a possibility, but I would assume someone with the resources to pull this off is smart enough to realize that it would quickly be discovered if the whole thing is bs, especially as the story involves some of the US's most valuable and powerful companies.

Also, why the need to make up a false story to make China look bad? There are plenty real issues that make China look bad. Before I get accused of some anti-China bias, the same could be said of the US. If I wanted to make the US look bad I'd focus on any myriad of foreign policy or domestic concerns that show it's failings before I concocted a story that would soon be discovered to be a fabrication.

But that seems even more bizarre. Who has the resources to do that but not the resources to come up with a cleaner frame up than this? If the aim is to make China look bad, why target a US company (Supermicro) instead of a Chinese company like Huawei or Lenovo?

If the responsible party is not American (or is American but has a vendetta against America too), then why not? After all, the allegations said that some very high profile American companies were compromised from the hack, so why not involve another one?

Besides, it's more shocking if the Chinese hacked an American manufacturer rather than a Chinese one (where they would't necessarily have to "hack" anything, just compel the manufacturer to do it)
