I disagree on every single line.
This is not about software. Having the software on its own won't help you.
If in 2006, the year before the iPhone came out, you had the software as FOSS, would that help? There was no hardware yet. There was nothing even with a capacitative touch screen with multitouch yet. The whole point of the design was to do away with styli, but all extant touchscreen devices needed styli back then.
I was implementing corporate networks in 1991. I built them with NetBEUI for PC-to-PC comms, and IPX/SPX or DECnet for talking to servers. Occasionally all 3.
If I gave 1991 me the source of timbl's WorldWideWeb, it would be no use. I didn't have NeXTstep. My corporate workstation ran X11 and talked to servers over it but it didn't run TCP/IP. I had no TCP/IP in the building.
The point of the Web is the protocol, having clients and servers. Having docs is much more use than having code. Code is useless fragile stuff.
Android reproduces a lot of the interaction model of the iPhone but it came from seeing iPhones and trying iPhones. It did not come from getting source. Nobody ever got the source.
Forget the source. Source code doesn't matter. It's an irrelevant distraction.
Source code is not the big deal here. Inventing a new way to interact with computers is the big deal here. Getting at the software does not matter.
If have taken the time to understand what he means when he says "Realtalk is not made of source code", and disagree with his conclusions, that's not quite the same as him being dishonest.
