This is why you are not the finance guy.

My finance people care about the cents, a ROI of 7% is average but at 8.5% and now you are a world class asset of that inventory type. That’s sometimes the difference of a few hundred k out of 20m but they would not take the deal if it is slightly over due to their risk appetite.

The 3b external either matters a ton to fit their risk models OR they are doing a favor to an outside party. Probably a bit of both.

Well, given that it is an equity sale, split still feels like it is the prorated amount so that alphabet continues to own its percentage - not more not less.

Obviously you're entitled to your view, but I don't think it's that kind of finance model right now - it's far too speculative and the upside too unknown to be adjusting for small amounts on risk models.
