The six strike ant-piracy rules being enacted by most US internet service providers (ISPs) could spell an end to ubiquitous free public Wi-Fi. Not necessarily because cafe’s are liable for what their patrons download, but because most of them are sharing their Wi-Fi illegally. The six strike provisions contain exemptions for legally shared commercial broadband service – a considerably more expensive product than everyday consumer broadband. Unless cafe’s are willing to pony up the extra dough each month, they will be treated like the average consumer and dinged for each illegally download of Ke$ha’s latest single. [Source: TechDirt]
