It has been established that she had already been considering a move to Germany. That is not at issue here. The issue is whether or not she timed her departure to avoid contact with the FBI. If she did, the article's premise is justifiable.
She bought a return ticket she did not intend to use, to throw the FBI off her trail. She would not have done that if not to avoid the FBI. Given this, and her own statements in the CNN article, the evidence that she timed her departure to avoid contact with the FBI is overwhelming.

It's not like she just impulsively thought about Germany and left that week. Yes, it was a catalyst, but it seems to me that she was already on the fence, ready to leave. She even said she was waiting for her visa approval to be accepted after the FBI had made a request to interview her.
