> In the US, internet provider are regulated as utilities and are stripped of any power on the content they serve, and the platform thrived as a result. What would Internet look like today if AOL had applied Apple's policies?

About the same as it looks today. AOL was a walled garden, and unregulated internet was so compelling that AOL was forced to offer it, or die, like so many other services did; of course, AOL still pretty much died, but it lasted the longest of the pre-internet national information services. Incidentally, that was back when it was easy to switch between competitive ISPs or set up your own and there was not much in the way of regulation. Now, we live under the threat of the cable and telephone companies pushing their products. Not a whole lot of clear regulation now, and not even the basis for local loop unbundling like congress provided in 1996, but the FCC watered down until it meant hardly anything.
