I'm not certain how I would use people's wifi passwords without being at their home
Doesn't Google track router SSID names and MAC addresses? This definitely used to be a searchable database that was connected to Maps. I can't find any of the old websites but it looks like it might still be accessible via API.
but I'm certain somebody on Hacker News could tell me exactly why it is a bad idea to share your wifi password to the internet.
Not a hacker but I'm going to give a easy but not critical example. If you have access to another device in range (say, because you run a botnet) you can jump into another neighboring network. I'm sure someone on HN could give us a much more worrisome example.
