Can also testify to this, also works for transferring files to the device from Linux if app supports (ref VLC, etc). However, the speed is mind-numbingly slow.

Faster and easier to just sync with iCloud, then download from iCloud.

So, why not just vote with my wallet, and get a device that either is more friendly to 3rd party software interaction or simply allows saving to a movable SD card? Because overall things work very smoothly, and it is easy to find and manage settings. These things balance out well against the frustrations, especially when I know from experience that non-Apple devices will present their own frustrations.

To be fair, the philosophical/theoretical/economic foundations of antitrust legislation confuse me. This has not been helped by media bites a la NYT. Maybe if I had months and years of free time and good material I could form a worthy opinion. But for now, I just have trouble seeing how statements like this from OP are contradictory: "The company says this makes its iPhones more secure than other smartphones. But app developers and rival device makers say Apple uses its power to crush competition."
