And none of that money goes to the people who historically lived there and were displaced.
So... that's a pretty shitty thing to support (as someone registering a domain), when the alternative is simply "Pick a different TLD."
Tbh, ICANN/IANA should either (a) dissolve the TLD as-is, as there is no independent country it covers (and the UK already has one and doesn't want it) or (b) switch it to Chagossian ownership, so they financially benefit.
The current situation and ownership is indefensible.
