Guys don't get upset at the author for wanting it taken down. I'm sure if more authors knew they'd want their works removed too, regardless of official translation status. It's very shortsighted to assume just because most works get illegally uploaded and translated that everyone is okay with it and won't be willing to pursue legal action.
It's within their right to want it removed. Others have been removed from the site before, this isn't a first. The least we can do is respect their wishes.
