The AP style book now says that the Internet should no longer be capitalised.

Vint Cerf, the co-designer of the network, disagrees.

The editors at AP fail to understand history and technology,” Cerf told Politico on Wednesday (June 1). His beef is that there has always been a line between the public internet and a private internet that has no connection to the outside world, although it shares the same TCP/IP protocols. This, he warns, is simply daft. “By lowercasing you create confusion between the two and that’s a mistake,” he wrote.

I agree.
