Z:gnu-www-ja-thegnuproject--f82087-As the GNU Project's reputatio/en

As the GNU Project's reputation grew, people began offering to donate machines running Unix to the project. These were very useful, because the easiest way to develop components of GNU was to do it on a Unix system, and replace the components of that system one by one. But they raised an ethical issue: whether it was right for us to have a copy of Unix at all.
