So companies A & B (A=TSMC, B=Tokyo Electron) are in a customer-supplier relationship. Employee B1 of B asks Employees A1 & A2 of A ask for information about how B's technology is working in practice at A, which involves revealing information about A's processes. A1 & A2 supply the information, and B2 at B uses it to improve how B does things, so they can help A more and increase their business with A. There is no allegation that the information supplied to B by A employees left B, or was used for anything except to help with the collaboration between B & A. And as far as the article mentions, no evidence A1 or A2 received a bribe or anything like that.

And yet manager A3 at A finds out about this supply and freaks out because they didn't want A1 & A2 sharing that much information with the supplier. So they make a complaint - and A1, A2, B1, B2 and B as a company all face significant penalties.

This seems unjust given A1, A2, B1 & B2 were all just trying to collaborate in the best interests of their companies, and B employees only used things freely and non-corruptly given to them by A employees; no information was leaked outside of the collaborating companies. A1 & A2 might have broken their company policies, but this probably should have ended at them being educated on the company policies and being asked not to do it again when managing future supplier relationships.
