Well, there are many different... idealogical alignments in America.
Some believe Manning is a hero who followed her conscience and leaked classified information in order to inform the public of secret crimes the government/military committed.
Others think what Manning did was incredibly reckless and treasonous, tantamount to selling secrets to the enemy (just without the "selling" part)
So to answer your question, people in the first camp see news like this as a good thing.
I don't think this should be reduced to her original actions. She was sentenced as a consequence of them, she served 7 years until the rest of the sentence was communted by Obama.
So the real question is: was it appropriate to throw her back into prison, under very harsh conditions, just to force a statement from her. I think there is very good reasons to doubt that, independant of the stance about her original actions. From that perspective, I think her release is good news.
