Yes! Thank you, @doctorow for following and raising the issue of binding arbitration (and its evil twin, removal of class action rights) and adhesion contracts in general. They are everywhere, and I’m not sure why people aren’t raising this as the important issue it really is.
I commented about it here last week, and even talked about what was mentioned here wrt the opt out provision, specifically, that in order to opt out, or even “send notice”, it has to be done in a most manual and inconvenient fashion (ie, postal mail). But of course, the organization can send notices electronically, in a most convenient manner.
