To be fair, Galio has apologised multiple times (not for the wording, but "if you feel offended") on the letter's meta talk pagehttps://meta.wikimedia.org/wiki/Talk:Wikimedia_Argentina/Open_letter_regarding_URAA. There is much discussion there of what was really meant, and the problems with the letter's wording.
I think WM Argentina has a legitimate point to make about the wasted work of its members, so it's a shame that it was expressed in such a way.

Still no explanation (nor appologies) on usage of inappropriate wording towards volunteer by the board of Wikimedia Argentina.
It quite amazing when almost all projects have policies on civility ...
