It is a difficult question. One example that always springs to mind, was Australian friends online in the early 2000's who told me their ISP had linux mirrors - which was of great value to them, because they were charged less (if at all) for data within their ISP's networks. They were also much faster, since it meant the data wasn't trans-oceanic. Later Steam came up as another example of the same idea. They thought this was fantastic. It solved a lot of problems (and expense, and speed) for them. But it's not particularly 'neutral' either, is it? Given the choice between a distro that's on my ISP's mirror, and a distro where I have to slug data from the other side of the planet, I'm going to make a choice based on my ISP's preferences. Putting a wikipedia cache/mirror within the ISP's network would, in this example, render pretty much the same results as "wikipedia zero". Same benefits, same concerns. I'm not really arguing this one way or the other. Just that it does muddy the water when we have examples that benefit the enduser, to counter the scarier examples we see elsewhere.
