I think he spelled "Money and control" wrong.
Each sideloaded app is a cut not collected by Apple. It's also a potential vector for a UX-breaking experience. Both of these go against the vibe I've gotten from Apple since pretty much the beginning.
It's not like their position is without merit, I've argued multiple times that their way has its advantages. They are essentially saying "in exchange for some more control/restrictions on the system, we are essentially guaranteeing that a given device/app will work as intended (until planned obsolescence kicks in anyway)"...
It's the same reason I am a console gamer as opposed to a member of the PC Master Race. Yes, the PC can potentially be much better, after investing effort, time, money, etc., but I know when I get my Xbox, and I get an Xbox game, that it's gonna work on that Xbox, or it's on them to make it right, not me. I am willing in this scenario to give up that extra power/performance/flexibility for a consistent and confident experience.
That said, I'm an Android guy. Have been since the early days of looking through the glass at all the nice "made for iOS" gadgets that didn't exist for Android because developers couldn't/wouldn't develop the hardware and software to handle all the differences in the fragmented Android space. That's not so much a selling point now, but it certainly was at the time. While I'm by no means a "power Android user", I do enjoy the ability to root/sideload/otherwise customize my experience on Android, and do play in that space from time to time. I don't begrudge those that want to have the walled garden up for themselves or their loved ones, but I also don't believe for a second that it's about "security and privacy".
