The amount of pro-colonial sentiment in the thread here is baffling. The people that were colonized and stolen from have the right to do whatever they want with these artifacts, even if you believe they may not have the means, or will sell them to private collectors.
Why not just accept the situation as part of the ebb and flow of history? They certainly weren’t the first empires in history. I think a lot of the objection is more about nationalistic sentiment than anything else and I don’t feel it needs to be done to reclaim cultural heritage.
Hacker News is comprised almost entirely of privileged people from colonizing cultures, and tech culture has been going through a neo-reactionary renaissance for a while, so it shouldn't be surprising. It is weird how aggressive this specific subject makes them, though.
