I've seen a few people (some making vlogs) whose eyes seem glazed over with $$$ signs.
Watched Vin & Dave's show (#19) and Vin gave some really useful background about the scene.
I believe he correctly touched on the psychology going on there, and Craig and Calvin's strategy to deny service on the "ABC" chain to push the price down as far as they can to drive other miners to surrender.
This is of course a harsh thing to face, it's pure intimidation, brinkmanship etc etc
Craig's letter is probably just the tip of the iceberg here.
To defend, some ideas:
Technically, to recap the idea there is that they will mine empty blocks on the attacked (ABC) chain with sustained majority hashrate in an attempt to deny as much service to the chain as possible.
Very likely they'll use the stress test (blaster / Satoshi's shotgun) to keep the mempool filled at > 32mb / 10min while they do it.
Defending miners could (and imo should) raise the minimum fee level (with announcements) to defend and make this two-pronged attack much more costly for the stressers. Let them figure out that they should conduct their tests some other time than during a network upgrade. That was obviously coordinated with the 'hash war' crowd.
Users who wish to help honest miners defend the chain against an empty block attack (any of you around? ) can also voluntarily and temporarily increase their transaction fees - which directly helps make mining the chain honestly more profitable, allowing other miners to bring more hashrate on to it which reduces effectiveness of the empty block attackers.
It may be a small price to pay compared to letting such financial terrorists and their backers take over the network.
