I have had some (sad) experience with this sort of large-company extortion in the recent past, although it was a more expansive intrusion, IMO. My company designs/builds optical measuring systems using interferometric principles, for sub-nanometer shape mapping. We received a PO from a large global corp., based in US, for (2) systems which had a total value in excess of $100K., and it was an application that was perfect for our gear. Along with the PO, there were links to the customer's code of conduct, which was a lot of ESG requirements, and instructions for the "onboarding" process as a new supplier, for which we would need to pay a $1K fee. Our quote for the systems states that our terms and conditions will be the governing T&C's. The PO stated that their T&C's would govern. In reviewing their T&C's, there were explicit statements that we would be responsible for adhering to their code of conduct document by accepting their PO, and ensuring that our supply chain would also do so. We went around the barn with their legal reps trying to fix this, and finally ended up refusing the order, because they had no ability or interest in removing the offending language, and thereby coming to an agreeable situation. This was very painful for us as a start-up company, still trying to get our heads above water. I think it's a fine thing for companies to aspire to make the world a better place, generally, but to mandate that your supplier must do so, and ensure that THEIR suppliers will also, is just madness.
