Re: "New IP 'would enable mass surveillance' "
"People do very bad things on the Internet, and they need to be stopped, eg Huw Edwards."
Didn't downvote, but would like to point out that for all the bad that happens on the internet, worse happens in real life. Where do you think those pictures came from?
"Free speech shouldn't be allowed"
Free speech should be rolled back to its original meaning - you can call the king (or president, whatever) a dickhead without worrying about spending the rest of your life eating gruel because the recipient with the fragile ego stamped their feet in a dramatic manner. It shouldn't have ever become an excuse for justifying "I can shout louder than you", because honestly most of the shouting (also fragile egos stamping dramatically) is not worth listening to and it only serves to exclude the rational who don't want to have to deal with all of that nonsense.
"'freedom of expression'"
I don't know how it works in law (probably depends upon jurisdiction), but I consider this to be a separate thing. Freedom of expression, for me, would be that I can wear a shirt with the flag of Palestine (or, let's be fair, Israel (or Ukraine...)) and that is my way of expressing how I feel. But this doesn't give me any right to go online, or worse, in real life, and yell "wanker!" to whoever may be wearing a shirt with the other flag on it.
"with legitimate interests"
First hurdle, define "legitimate". This sort of thing gets real messy real quick.
