So it is not normal/correct to have an agreement with a partner that excludes others?

They don’t have agreements with graphene so what do they care? Google owes graphene absolutely nothing.

They care about their partners and about following the law. Google is not being spiteful here like some commenters are saying; instead, they have changed the way they work to make it compatible with a new law that applies to them.

It’s tiresome to see the same kind of snarky comments in every thread because they are not interesting at all. They are just lazy, and begging for votes.
