Widespread use of DMARC will result in changes to well established conventions. I don't personally object to having the list server rewrite the "From" field and add a "Reply-to" header that designates the original sender; but some people have needs which differ from mine, and for them it can be an inconvenience.
Yes, it also has the potential to reduce the distributed and decentralised nature of email;
I.e. if you're not sending via a "reputable" service provider, your mail wont get routed. This is antithetical to an open Internet, Internet neutrality, and it could also be considered a means of censorship by some.
That's an interesting observation. On the other side, it isn't hard to set up a "reputable" provider. I recently did so by configuring SPF, DKIM and DMARC on my mail server. I am nevertheless concerned by the centralization of mail services in the hands of large providers, and likewise the rise of large social networking sites which merge the features of mail, instant messaging, voice and video services, among others - all in a proprietary manner that lacks interoperability. Then there's the data mining which takes place to enable the social Web site operators to monetize the activities of their users.
