You have to remember the attacker is spending good money attacking these eth chains. So they "pay-to-play". They are free to spend their cash as they choose.
Every time EF fork ETH a new coin is made. Soon the attacker will be fighting on
three fronts so they will have to work harder and spend more money doing sustained DDOS attacks on three coins.
ETH holders will have a another new (or should i say another old?) coin to exchange for bitcoin (or ETH if they are that way inclined).
Plus, GPU miners will have a another chain to mine for some fast profit too if they get in early. So win-win for everyone but the attacker. Lets hope for a 10% / 90% split again and a couple of easy and exciting months of mining a rogue chan like with ETC.
I love Ethereum. The way they get everyone fired up is fantastic. Nearly as good as the US elections (which we are enjoying greatly).
The best Altcoin by far for both entertainment and mining profit. I could be said, it is the best thing to have helped boost bitcoin so far this year.
