I have seen this happen to a few places where I live and I personally not affected but in the past I have experiences where it was to expensive to buy phones, data, internet so if i was lucky enough to get a phone I would always go around using the free internet to not only check my social media but to contact my parents for rides home or encase I am stuck somewhere so in that view I can see how people getting rid of free wifi is a pain but I can see why they are doing it to. You have to take in there point of view, they are going to internet company's and buying wifi for what maybe 50-60 bucks depending on there area and what company each month for random people who might now buy, or use appropriately for the place giving the wifi and so here is a question for you would you buy wifi for random people to use for what they want whenever or would you either get rid of it completely or put a lock so they cant get in and if they want to use it they have to use the device like a pc at a library automatically hooked to the internet?
