No, they went to Facebook after MS made their offer (when the article came out). That was just Bobby making his due diligence to show the shareholders he checked if there was another offer (to get a better price).Activision went to Facebook first. They said no. Kotick literally went to Spencer. Spencer went to Nadella. Nadella basically said hell yeah and well, here we are. Of course, the Kotick/ABK shit led to them selling but who's fault is that? Microsoft's? LOL. That's Kotick's fault for being a fucked up human being who saw a way out while getting a massive payout.
It was all explained by @Three in the GAF thread with the SEC fillings. You are active in that thread so you should have seen it.
