Bad choice of term. You're not surrendering anything. You have a tool that can calculate optimal exposure in a thousandth of a second based on a multitude of different input parameters, there's no reason not to use it, much in the same way that you don't NEED to rely on autofocus, you can use manual focus.Auto ISO is the same concept; you're surrendering control of the exposure to the camera.
I find it odd that some photographers think that you need to shoot in M all the time or you're somehow not a real photographer. I'm probably shooting mostly in Av mode except in the rare case that I'm after fast action, and then it's Tv. I use M mode for things like macro photography where I'm taking shots slowly and I'm more in control of the variables, or on studio shoots where I have a specific studio flash speed/power dialed in. But all other times I let the camera deal with all that crap, because it's much faster than I am. And that means leaving it on auto ISO most of the time too.
With mirrorless cameras and more intelligent scene analysis AI, the camera's ability to get a better exposure than you can do manually is only going to increase.
I'm all for those starting out in photography sticking with M for a while as a tool to understand properly how the camera works. But once you've mastered that, using the camera's capabilities properly isn't cheating at all.
