I find your example illustrates the point . The UK has insane libel laws
The sane solution would be to address these laws, not to create mechanisms for people to arbitrarily evade laws
A lot of pro privacy arguments seem to boil down to "well we should make it a bit easier for people to break the law, cus maybe the laws are just bad". This line of reasoning just feels really unsatisfying..
It is somewhat strange since the tabloids are extremely toxic and spam gossip.
