Would You Connect to an Unsecured Wireless Network?

I personally would not use my neighbor's unsecured wireless home network without their permission. I just don't think that it is morally ethical. Just because my apple tree is next to the property line, doesn't mean my neighbor should pick the fruit off.  I keep my network secured, so if I found out someone was using my network without my permission, I would reset the password. I think if someone is sponging wifi, a verbal warning should be given first, then fines, and finally formal charges. If the cable company found out someone was getting free cable, the company would press charges against that person for theft. Those that leave their networks unsecured should not face punishment. In my opinion that would be like punishing someone for having their ATM card stolen. Just because you can access it, doesn't mean you should.

Employers and Facebook

I do not believe that employers should be allowed to ask for your facebook password. There could be sensitive information on you account in messages that you really don't want anyone to see. Things like how you feel after your abortion, how life has been since your gender reassignment surgery, or your strained relationship with someone. That is not anyone's business but yours and the person with whom the conversation is being held with.
I only see two ways to possibly combat this. Both involve telling your perspective boss you have no account. One way is to deactivate your account, this way you do not have an account the employers can snoop around in. The second option would be to use an alias. If your name is Sammie Joe, that is the name your employer is going to look for. If you go by an alias of Crappy Burritos, no employer is going to search for that.
