Value Added Services and Censorship II

Dear Sir or Madam,

You asked me to rephrase an earlier FoI. Perhaps the following
words will be sufficient?

It has been reported that mobile broadband providers are, by
default, censoring mobile broadband services to inhibit access to
legal web sites which are deemed 'unsuitable for children'.

- What protection against unauthorised censorship of legal
telecommunications exist in legislation enforced by Ofcom?

- What is the legal basis for operating such communication
censorship on an opt out model?

You ask me to clarify what I mean by the term unauthorised
communications censorship; I understand that without explicit
authorisation from users of mobile broadband services, legal
communications deemed 'unsuitable for children' are being censored.

Such communications are likely to include perfectly legal content
topics such as health information, sexuality, controversial
politics, age rated films, abortion, drugs, music lyrics, and war.

I believe that such services - as valued added services which are
not essential to transmission - should only be initiated only with
explicit consent from subscribers.

Yours faithfully,

P. John
