This situation doesn't really seem like it's "history" in the same sense, considering it happened so recently, governments are still actively working against them as they attempt repatriation, and the TLD issue is fresh.
I see some parallels, and time that has passed by is also a weak excuse. Even I think, that many native Americans also still suffer from the treatment their ancestors got.
But: You can't excuse one wrong with another wrong. The fight about the TLDs might be some little thing, but what happened to those people is an outspoken injustice and I can't comprehend, how modern countries could do such things in the last decades.
The comparison to native Americans is good, because it shows, that the methods are still the same, the deeds are just hidden better nowadays.
No, time that has passed is not a weak excuse if we are discussing something that is current and loosely involves many of us (the purchase of .io TLDs, an issue that only emerged recently) instead of having a general discussion about government abuses over time.
Nobody is trying to say that Native Americans didn't get a raw deal; only one person is trying to say that because Native Americans got a raw deal a few hundred years ago, it's OK to do the same to the Chagossians right now. This is the sort of logic people always employ when they're trying to feel better about participating in something shitty. It's the "But he hit me first!" of ethics.
