That's one solution. I don't think it's ideal. Not everyone would know to tick that box. I would, but my friends would not and their networks would be vulnerable.
It could also require buying new hardware. Once again, I would know to look for a Wi-Fi Sense-proof router, but my friends would not.
I also don't think we should be expected to solve problems that Microsoft caused. Why should the industry adapt to Windows rather than the other way around?
Maybe instead they could have router makers add a flag to opt in to this insanity. Then if people really thought it was important for their networks, they could ensure they have compatible hardware, and turn it on.
