I give my old magazines to a quilting friend--after I remove any patterns that I want to make. She knows that I do that and is OK with it. I also get her a gift subscription to any magazines that she likes--that way we each only pay 1/2 price. I don't know what she does with them, and I don't care. I can't bring myself to throw them away and don't have room to keep them. I told her to pass them on or throw them out. She doesn't tell me what she does with them so I don't have to feel guilty. Works for me.
