The difference is a contractual one. If I bought some program, and an Apple software update deleted it, I might sue them. And I might win. But if Apple uses the iOS kill switch, then they are within their rights.
The difference is similar to that between a plumber I call in now & then to fix some pipes, and a plumber who gets a key to my house, and my written permission to do anything he wants, whenever he wants. Both of them have the capability to rearrange my plumbing in any way they want. But the latter is scarier.
