Apologetic? All the big powers think that is nonsense in today's world where everything is measured in the "economy" you have.
A recent example, watching Mr. Sun flexing his muscles purely on the weight of his "wealth" to disrupt a decentralized chain, in the name of which, he is making millions.
So till the big countries (like the US) apologize to the natives, nobody else doing it (like Australia) matters.
So, the only people whose apology will matter right now, would be the Tron foundation/Justin/steemit Inc, I think.
