Shattered is the trust in transactions that happened during the time period where the attacker controlled >51%, from addresses that the attacker also controlled. AFAIK so far they haven't controlled 51% for any amount of time, though they did control more than 33% for a short while, which is enough for "selfish mining." Either way, the attack did illustrate that a government could easily take over XMR if they wanted to. The impact of that, we'll have to wait and see.
