Just saw this in an NPR interview. It’s actually something I do, as well. I don’t use public internet offerings from coffee shops or airports. It’s just too easy to get hacked, nowadays. If you can afford to do so, consider getting a MiFi and top it off with a VPN (virtual private network) service. There will always still be aggregated data about you but at least you can protect yourself this much:
I have a portable Wi-Fi device called a MiFi that I use in coffee shops and hotels and all the places that give you supposedly free Wi-Fi. The truth is, what we’re learning in today’s world is that nothing is free. If something is supposed to be free, then it really means they’re taking your data. So what I’ve decided: I have to buy my way out of it. … Privacy is becoming a luxury good.
