If you mean https://www.vice.com/en/article/9ke3ke/famed-computer-scient..., please note that that article misconstrues what was said.
Both the headline and the article claim that Stallman said Giuffre was "entirely willing;" a read of the provided emails shows otherwise. He said that she probably appeared to Minsky to be "entirely willing;" that Minsky would have been unaware of coercion, not that there was none.
There are absolutely things to object to in what he said, but we should be objecting to what he said, not the words some (apparently) shoddy journalists are putting in his mouth.
