I think I'm confused on the "stupid" part. I've downloaded things from the Shopping channel many times over the years, even with a modded Wii. I grasp the concept of keeping IOSes up-to-date and such. Yet, with all that, the Shopping channel fails to download Netflix, but does download the web browser channel.
There are only a couple threads discussing this new update from my searches. I have read them. If you are meaning the input lag, that isn't relevant to my original question. In my case, the Wii is just used by my five-year-old to watch Netflix cartoons and play one or two games. The Netflix for kids update would be useful in this case. She is slow with the remote and doesn't need to flip through shows at 100 mph.
I hope that helps you. Have a good day.
