I can (maybe) understand why they did what they did.... as they were pissed about their stuff being stolen. Not saying it was right or anything, just that it seemed 'right' to them at the time.
What I think is woefully unacceptable is their response to their own mistake.
They apologized. ok.
They posted a retraction but then removed all posts (including the retraction) within 24 hrs? not ok.
There has been no offer beyond 'woops!' to make it right again.
Based on that, I think they've assured themselves of an imminent lawsuit for damages.
