Management doesn't care if it's agile or not - they want something that works and delivers economic value for customers and will help them continue to innovate and deliver EVA for them in the future. One huge problem is that a lot of times, what people think is what the customer wants isn't what they want or need. One way that happens is sales brings asks (in the form of solutions often) to product and it goes downhill from there. Obviously, the people doing the work aren't talking with customers in that case, but it's tough to talk to customers in an enterprise environment. If you're doing something for a small external client or an internal team it's fine.
In addition, customers aren't a monolith. When you reach sufficient size, you have competing priorities for customer needs and even some asks that work for one customer but break some sort of process for another. They can be mutually exclusive. This is also heavily predicated on the customer even knowing what they want. Everyone knows the famous Ford quote “If I had asked people what they wanted, they would have said faster horses.”
Agile is great but scaling it can be rough dependent on a lot of variables, so reducing it down to management probably doesn't like Agile due to inability to give up power (to me at least) is a bit too simple.
