> There has to be more to the story here. With the law starting in 2006, why are authorities just now going after these bars?
The law states that businesses must keep some log in case an investigation about patrons' net usage requires it. It's not checked every day, but when an investigation happens and you got nothing to show, you get prosecuted.
Pretty similar to accounting, the minute details of your accounting won't get checked every year, but you must keep them available for the tax service.
The difference being that you maintain your own accounting records, and any discrepancy is a result of your own failings, whereas WiFi logs can be expected in practice to contain entirely fictitious information for the majority of ordinary users due to no fault of the cafe. Which makes them totally useless and any requirement to keep them a wasteful burden and a trap for the unwary with no countervailing benefit.
