No they are not. The filtering scheme covered in the submission is the Under 12 O2 filter, that is a filter designed for parents to enable (it's opt in, not opt out) when they wish to give their children access to a mobile device. That filter scheme uses a whitelist, every single website is blocked by default until a person at O2 adds it to the whitelist. This service has existed for many many years and has absolutely nothing to do with the government, it's a feature that O2 added for their customers. O2 do also operate a porn filter, but it is not what this article talks about, it does not block tech articles and civil liberty websites.
The article that you have submitted is FUD. Read this: http://news.o2.co.uk/2013/12/24/parental-control-questions-a...
I feel I explained my rationale and there can be no more constructive conversation in the particular thread. As for the article being FUD, sorry darling I guess we'll have to disagree on this one.
The government's job making a law of(and therefore enforcing) the above is easy to justify under the rationale that this thing existed for years(with a few specific ISPs). Now everyone will have to do it, and on top of that it will be the government that will be defining what is 'Obscene and Tasteless' as opposed to a mere ISP.
I understand what you mean too, but my disagreement genuinely has to do with me seeing that both filtering schemes are identical to each other and have the same purpose and effect. Both are opt-out and both do not have to do with pornography only. I sincerely do not see how these can be different.
