Because if there's something proprietary running on it, how are you going to "install anything" without breaking the proprietary parts? You will not be able to replace the kernel, you will not be able to upgrade any library (not even libssl when the time comes, and it will come), you will not be able to customize the software to your liking, etc.
You lose half the benefits of having an open system in the first place. I will have exactly the same issues than I do when a run Google Android: no control over the device. You're 100% at the whims of Sailfish.
And as for "OSS Android" still having unknown Google stuff, I disagree.
