Difficult for them though isn’t it? In reality, they can’t do anything but line up behind any plausible peace proposal that is brokered by another country. We’re not in a position to be the mediators this time.
They can’t come out and say they will do something specific (unless it’s just words, strongly condemn etc) because it will be hung around their necks when it doesn’t happen.
Just a small note that the businesses only have to open source their version if they release it. If they just use it internally then they don’t have to distribute the source code. So it depends on the use case.
