OK, I admit, I couldn't read past this sentence. This is so much complete and total bullshit that I closed the tab in disgust.
The ability to sideload apps on a non-rooted, non-jailbroken device is exactly what any and every device I own absolutely must support and this is non-negotiable. If I own a piece of computing hardware, I will have the freedom to install and run any software I want, regardless of where or how I obtained. Oh, and I don't use pirated software.
Given that people are already talking about a "war on general purpose computing"[1], it's downright shameful for this guy to run around promoting the idea that open devices are designed to enable piracy.
