Throwing computing resources at it can be fairly accessible to small groups or even individuals as a result of 'cloud' computing. There are examples of people coordinating a large number of cloud instances for a short amount of time to crack hashes, and it was surprisingly cheap.

I don't have a reference on hand though.

This also makes it trivial for nation states and larger groups to decrypt whatever data they're able to sniff. It would actually encourage more groups to get into more places where they can sniff more data.
