It's such a complicated, messy situation, isn't it?
Regardless of whether the allegations have merit or not (and I don't even like saying that, tbh) the authorities are clearly using the situation to attempt to force him to change location - it's patently obvious. If all they cared about was extraditing him to discuss an allegation of rape (worlds first?) then they'd have made it work given the circumstances - they could have got him on a conference call ffs - why does he have to be sat in an interview room in Sweden? Assange has admittedly offered to accommodate the investigation up to the point of leaving the embassy. Any organisation that was only interested with seeking justice for the women involved could have made that work, surely? Ordinarily of course that would be absurd, but this is a very special circumstance.
But they didn't. They haven't charged him, they haven't attempted to engage with him properly without an extradition. Edit: This may or may not be true, @Arduenn makes a point that blurs that a little.
I just really, really hope that the allegations aren't true, not for Assanges sake, but for the women's - as they will have been used as a pawn and not even got the justice they deserve.
But regardless, the bad guy in this situation, really, is the authorities. Who have only been interested in forcing Assange out of hiding, not getting anyone justice.
