Is it necessary to purge the wife when dispatching a #MeToo offender?

“Sex Abuse Scandal Casts Shadow Over Nobel Prize for Literature” (nytimes) has a slight twist:

the newspaper Dagens Nyheter reported that 18 women had accused Jean-Claude Arnault, a major cultural figure with close ties to the academy, of sexual assault and harassment. Mr. Arnault is married to the poet Katarina Frostenson, a member of the academy, …

Ms. Frostenson has refused to step down from the academy, despite calls for her to do so. In a recent closed-door vote, eight members voted to keep her on the board and six voted to oust her. (Ms. Frostenson did not vote.)

Presumably the wife did not endorse any sexual activities between her husband and other/younger women. Why then does she have to be purged?

[Separately, if you were looking for a definition of “not woke”:

Worsening the scandal, new evidence has emerged showing that as early as 1996, a textile artist, Anna-Karin Bylund, complained to the academy’s top administrator at the time, Sture Allen, about sexual harassment by Mr. Arnault. Mr. Allen, who remains a member of the academy, has said he did not act on the letter because “the contents of the letter didn’t seem important.”
