It appears that UK Prime Minister David Cameron is announcing that any place in the UK that provides WiFi to the public must block porn. This is wasteful and pointless for a variety of reasons. Of course, it‘s being pushed under the „for the children“ banner, but that‘s rarely true or accurate. The problem, of course, is that (1) such filtering tends not to actually block plenty of porn and (2) it regularly leads to collateral damage, including plenty of legitimate sites being blocked. Plus it‘s just costly.
