It seems to be Ofcom policy to publish responses after the consultation closes - which is a shame - but they finally have published the 97 responses on net neutrality. I am hoping a keen PhD student out there somewhere will go through them in depth but I recommend reading the special pleading of the GSMA on mobile neutrality, which includes this beautiful couplet on p12: "Operators want to apply open principles to deliver choice, innovation and differentiation. Operators don't want the potential of the internet to be stifled by an indeterminate openness concept." Translate: get out of the way, we'll choose who can use our network.
Elsewhere Damian Tambini has written for The Guardian on why Ofcom's position is untenable as regards this issue - it timidly claims all wider remit questions are for government, while government has told the EC that it should be up to NRAs how they respond! I think they mean they don't want to do anything much?
