Android is only the dominate player because everyone stopped writing their own software and started freeloading off of Google.
Now they want to freeload off of Google AND not allow Google to profit from it.
If it doesn't benefit Google, why exactly does Google want to support Android?
Android isn't free, thats the first mistake people make. It just doesn't cost any cash up front, but you pay by turning your data/customers over to Google right out of the box. At no point was this hidden from anyone.
I really don't see how Samsung has a leg to stand on, they don't have to run Android. Apple doesn't. Windows phones don't. Samsung didn't use to run Android or have a Google Play store so its hard to argue that they can't find an alternative considering they used to use alternatives until ... they all agreed to use Android under terms and conditions they've been using for years. Now suddenly its a problem?
Google could just drop Android support entirely and the field could devolve into even more chaos than the Android landscape already is, is that a bright idea for Samsung? Do they want to let MS regain a foothold again?
Samsung gave up control over the OS when it stopped paying for the OS under its terms and instead started freeloading off of Google and became bound by their terms.
They did this to themselves, intentionally. Fuck'em.
