It's not just apathy, it's deliberate
Here in the UK, the big providers have all hoarded IPv4 addresses, and if you start a business and want a good sized block, you need to buy them.
This gives the old guard a competitive advantage, so it's not in their interest to promote IPv6 adoption.
Where it suits them, you'll see IPv6 usage. BT and Sky now have it enabled by default on consumer services. Some mobile phone operators use it, they have so many attached devices that rfc1918 addresses were exhausted on a national scale.
