From the announcement quote seen on ThinkBroadband, the Minister expects them to adopt some voluntary code, otherwise legislation would be used.
So the ISPs don't really have much choice, and to be frank, if it ended up costing several million, the ISPs are not going to be any worse off in the long run because they will recover the cost from the poor schmucks who are customers, a significant proportion of whom would want no extra expense and definitely want no damn filtering. (Do you really want to make the internet unaffordable for some families?)
You've already seen that merely placing a block on porn (even if that is the most supported idea from past threads) does not address the need for a "family friendly" internet service which would also block 'rotten.com' (never seen it, but two adults saying it is awful is good enough).
If this proposal manages [for sake of argument] to block 95% of porn [unless someone uses a free proxy server] it still fails to provide a "family friendly" internet connection safe from viewing 'rotten.com' and other sites which might be better not viewed by children.
No, Snorbs does not argue against any household wanting to protect against under age viewing of porn, but equally, sees this proposal as tackling only a [sizeable] portion of what is undesirable, without affording parents the level of control unless they still add some blocking software so 'rotten.com' and other sites cannot be viewed.
I don't think anyone here has ever suggested that they don't want children protected from porn, but the objections are that forcing all UK ISPs to switch some sort of filtering on, to achieve a block on porn, is going to lull parents into thinking that the job is done.
It's only a partial solution to preventing children from seeing family un-friendly material, and to do a proper job still requires parents to make the effort and if society needs to do anything, it isn't to do this 'blocking at ISP' filtering thing, but educating parents who have internet access to do more themselves.
All through this and the other thread, parents with hands-on experience of filtering software, have said that filtering at the ISP is not the solution and that there needs to be a change in attitude so parents take more interest and get on top of the technicalities.
Rather than allowing parents to abdicate their responsibility, which is how this sounds, you ought to reverse your stated position so the "other approach" is one of parental education.
You have used the excuse of probably being too busy, though I suspect that is also the case even among those with some filtering software already - there was a complaint about how much time it takes to determine what can be done for the XBox, iPod Touch, etc.
