It's probably inevitable. TV was free airwaves for so long. Now it's cable subscriptions. (And there's still advertising). Internet is already controlled by your ISP, so I have a hard time seeing that being "open" for much longer. Browsers, content providers, etc will all be regulated / commercialized / sandboxed.

Free zero-revenue startup idea: there'll be an IP-over-ham-radio or something to preserve "internet classic". (Largest use will be bitcoin-for-pornography).
