You are right about this and we have discussed about it on this forum often, but your topic about it after a long time ago is also good so that many newbies can learn from it.
Yeah! I know that op is right base on security purpose..but if you don't have what that will be expose through Internet in your device, I dont think that it's important be that conscious by ignoring the WiFi offer...
When I rent hotel room which is the place I noticed I am being offered free WiFi, I just decline it. I have enough data already and it is a huge amount of data.
You can decline, because you have some certain documents you need it to remain in privacy...but someone who doesn't have anything that's keeping in privacy will use their signal....Another thing we should know is that not all the cyber cafe you connected to their network can have access to your information...And they can't have access to some of your login..we dont need to be getting scared of free WiFi like that...
