The reason for the change was simple. Placing the WiFi receiver and antenna within the power cable provides a much better WiFi experience. Better reception, faster connection speeds. Yes, it's a tradeoff if something breaks. That's simply something you have to decide for yourself if it's worth the improvement. If not, you can use an Express 4K+, which is just as powerful as the Stick, and supports adding an Ethernet adapter via the USB power port.
That said, even though my Ultra has an Ethernet port I still use WiFi. That's because the Ethernet port has a max speed of 100 Mbps (which is more than enough for any online media) while I can get 230 Mbps using my WiFi connection (which is needed for my UHD ripped movies on my media server).
