My wifi post has certainly annoyed people far smarter than I.
[dead links, sorry]
So, here’s my deal:
1. if you run a bowling alley, my advice stands.
2. if you have data fears, my advice about asking a computer guru to protect your data still stands.
3. if you read the New York Times, my reaction to their fearmongering still stands
But, if you read my original post as saying that without any precautions, you ought to just make all your wifi hubs public, then I withdraw it, with prejudice, immediately.
