What does the EU want here, exactly? For Google to close Android and make all the phones itself, thus eliminating the problem of OEMs being paid by eliminating OEMs entirely?

This is yet another bizarre ruling by the EU - they're saying that a far more proprietary, less competition friendly approach (Apple) is OK, but you can literally give an entire OS away as open source and it's illegal? I don't think tech firms can win here. Nothing they do will ever appease the EU.
