The BBC, as ever, treads a fine line as a publicly funded broadcaster - it has a tendency to err on the side of caution in its rulings, but it also has a tendency to update its guidance in response to events like this. It's decided, from the wording in that article at least, that she broke their guidelines that were in place at the time, but it also suggests that there is at least some sympathy for her point of view - part of the issue is likely the nature of the programme she's on, and the role she's supposed to be playing on that programme, where it's not the nature of her opinion that's the issue but rather the fact that's she's supposed to not be editorialising in that particular moment.
I agree with her completely, and I think the statement makes clear that no-one in the judgement is actually disagreeing with what she said, I think there is a slight issue with her timing and how it fits with her job in that particular segment.
