Amazon was in a unique position to do it. MS or Apple could do it too but they have their own backyard to tend.
Samsung is a hardware giant. They suck at software and can barely handle a thin customization layer on top of Android and anyway they seem more interested in flooding the market with hardware rather than consolidating.
The other Android players are not making any money, building the backend infrastructure to compete with Google is a billion dollar type project.
It also takes time to determine what is abuse and what is not. Especially in behind doors deals. The case of Google threatening licensee to lose their license if they ship unrelated product Google does not like would definitively be abuse plain and simple. But as most things people discuss on the net, that's just based on rumors, who knows the real dynamic at play.
