I have yet to see anything showing a clear relationship between those complaining and the bones.
I don't think any of us would like somebody digging up an ancestor without our permission, but nobody has proven who the bones belong to. As long as they are reburied, if they are being used to further our knowledge, there's not much harm.
They dig up our ancestors all the time.
This may very well be our ancestor. When you go back over 9000 years, there may even be some of your genes in this guy.
