Ease of removal? Cost of putting it in? Weight? I mean there'll be hundreds of these on just one small commercial passenger plane. For something not structurally integral, why go to the effort and cost when some plastic clips work fine if not better if they need removing regularly? Works for a laptop case or phone screen - why not a protective cover for a plane window?
Aesthetics is the answer. You will see almost no visible screws on the cabin of an airplane. Or even a car. Designers keep screws and other hardware away from customers eyes.
