IPv6 is not some money-grab from the corporations trying to keep the people down, actually it's quite the opposite. The networking companies would like nothing better than to sell lots of carrier-grade NAT boxes to deal with the IPv4 address space crunch. The media companies would love to have every user behind NAT, because it kills P2P file sharing and restricts content hosting to those with the means to procure public IPs. An IPv4-only Internet will inevitably evolve into a client/server crap heap, where the users can run a web browser, and not much else.
There's nothing magic about IPv6; it's fundamentally just IPv4 with 96 extra bits. The IPv4 crunch gives ISPs a completely-legitimate reason to restrict your freedom, and IPv6 deployment is a clear way around that. Arguing against it is just shooting yourself in the foot.
Even if you don't care about upgrading your own IPv4-only equipment anytime soon, you should still want your ISP to be ready, so that when you find that you need a public IP (or a few billion billion of them), you'll have options available.
And places like Africa will arguably benefit the most from IPv6, because they have so few IPv4 addresses to work with, and their network deployment is just getting started.
