A few years ago, free and open WIFI was ubiquitous. Then cable and ISP companies started freaking out and shipping their modems with a password enabled (usually a 10 digit number, which can be easily hacked, so it doesn't provide security, just keeps 99.9% of people off of a network). The vast majority of people (again, probably 99%+) never change the default settings on their wifi, and so almost all home networks are locked down now, just as they were mostly free before. This move was entirely due to the American fear that a capitalistic cable company might lose a paying customer.
To all the silly people saying "this could never work" it already works in the USA in non-residential settings (I'd say well over half of all the restaurants, grocery stores, Home Depot/Lowes, auto repair, libraries, parks, etc.) have free wifi that I can use anonymously and somehow we don't have an epidemic of child pornography or whatever scapegoat reason to fear free wifi. And it is currently working residentially in many countries overseas.
The only reason I don't currently run free wifi is that my Tomato router doesn't support 2 networks and I don't want to open mine up to let the neighbors torrent movies. Not because it's illegal to torrent movies, but because I pay for the cheapest tier of service and that would bring my download to a crawl.
I'm glad Steve was in favor of free, open wifi, but I really wish he pushed it more. I never knew this was an issue of his, and if you ask the typical American, he is probably afraid it will allow people to "hack" you if you do it or some other nonsense. There is a lot of misinformation on this topic and if Steve or another trusted party had pushed it, we could have a lot more available wifi today. Although I think we are heading there. It seems that a new store or restaurant adds wifi all the time.
