Can you please elaborate? Your initial comment makes the point that no one is questioning Susan Fowler's allegations, that it's only one side, that her "blog post does not establish truth." That's the point that many other comments have made, whether it be about what happened at Uber, or more generally about whether the allegations are true at all.

At this point, the accused (or Uber, for that matter) is perfectly free to make some announcement if they so choose. I wouldn't expect them to—nor fault them—as it wouldn't make any sense, politically or legally, to do so at this point, at least until the conclusion of any investigation.
