This is the ESA's position: http://copyright.gov/1201/2015/comments-032715/class%2023/En...
I am broadly sympathetic to the EFF's position, but the ESA's argument is a lot more thoughtful and nuanced than the way the EFF is portraying it. I see this happening more and more with the EFF, and I trust their advocacy less and less because of it. It's one thing to be for a particular position, it's another to misrepresent that of your opponent in order to garner support. If you're confident of your position, you shouldn't feel the need to obscure access to primary sources so people can make up their own minds.
Oddly, while the EFF has multiple submissions to the copyright office as part of the open rulemaking process, and they're available on the EFF website, I've seen little acknowledgement of the fact the the Copyright Office is conducting a 3 year open rulemaking exercise on this topic, or about the Congressional committee that's re-examining copyright issues. I strongly urge interested parties to draft and submit their own arguments directly to the copyright office, where they will carry much greater weight.
