Yes, it was made public at this time for a reason. I have no idea about who made it public and why, but you can be sure there is a bigger game here.

Did the journalist and/or their friends and family make money on the massive drop in Supermicro stock?

Is the Trump administration asking to push this information out to earn favor in the trade war?

Are the investigators stumped and using this in an attempt to flush out new leads?

No idea.
