Samsung is already largely free from Google's egregiously anti-competitive licensing rules for Google Mobile Services. Why do you think it's going to survive for the rest? It's already unsustainable to have different rules for the largest OEM and that's without even taking into account future court victories similar to what happened in South Korea.
The MADA has been illegal for a long time, but you'll still find nobody willing to cross it. Samsung is indeed the only company with the power to actually escape Google and survive its penalties intact, which is why they are paid so lavishly to stay in.
