Which is, of course, false. AA has accused Assange of lesser sexual crimes, and SW has accused him of rape. There are no counts of rape against Assange concerning AA on the EAW, only three lesser counts (2x molestation and 1x unlawful sexual coersion). There is one count of rape on the EAW (count #4) concerning SW, in line with what the women have accused him of and also in line with what the Svea Court of Appeals has found probable cause for. Both women sought and retained legal representatives who have pushed the case forward for them (initially, both of them retained Claes Borgström, who was the one whose appeal got the closed portion of the investigation re-opened. More recently AA fired Claes because she thought he wasn't doing a good enough of a job with the case and was more focused on self aggrandizement; her new legal representative since started a new push to get Assange handed over to Sweden).
There's a lot more detail on these topics and more here.
The Assange-echo-chamber meme "Neither of the women involved have ever accused Assange of rape" is based on a simple distortion of a key element. SW (the one who the rape charge is concerned) didn't want to have to file charges - she only wanted to force Assange to take a STD test. She didn't want the thing to turn into a giant media circus that basically ruined her life and forced her into hiding from angry Assange fans. But there's a difference between not wanting to file charges and not accusing Assange of rape. She did accuse Assange of rape - first in conversations with her friends while coming to grips with what happened, and then went to the police station, where they told the officer on duty that they wanted advice on how to report a rape (see the statement by Linda Wassgren, the on-duty officer on the 20th). They were then interviewed separately where she described being raped, and after the interview she took a rape kit and sought a legal advocate (getting, ultimately, Claes). Since the leak of the Memoria file (a scummy act on Assange's side, I should add, as it's full of identifying personal details about his accusers and their families that have been used to harrass them - and we know it came from Assange's side because the cover page has a note to Assange's attorney telling him that it's confidential and must not be released), there have been a number of other followup interviews and investigations, and at no point have any objections from AA or SW been recorded. There is absolutely nothing in the record supporting a claim "Neither of the women involved have ever accused Assange of rape". SW has pretty much had to disappear after the event; AA went into hiding for a while but has since resumed taking part in some of the old forums that she used to; last fall she mentioned the case for the first time since the one brief statement she had given to the press after going to the police, mentioning offhand in an unrelated thread that a couple years ago she was the victim of a sex crime and that the perpetrator still hasn't been brought to justice, but rather she's still attacked by his fans for daring to report it. She didn't mention Assange by name, but it's obvious who she was referring to.
Most people who are raped don't want to file charges. They don't want the viscious attacks that come with it and want to shove the event in the past and not have to keep reliving it. A hundred times over when the accused is someone famous who has a lot of loyal fans. But claiming "not wanting to file charges" means "wasn't raped" is a massive distortion.
