We definitely should not talk about this
Not talking about it won't reduce the risk of it happening.
These people aren't stupid, are very likely to be aware of bitcoins, and have huge resources at their disposal.
A head-in-the-sand attitude won't help anyone. It's better to be aware of and address these (very real) possibilities rather than brushing them under the carpet and hoping it won't happen.
