I think the law would prohibit breaking into people's computers, not circumventing internet censorship.
By circumventing internet censorship you're accessing information that its owner wants you to be able to access. You're not breaking into their computer.
And it was not the Goverment who went against the users but Atari, Codemasters, TopWare Interactive, Reality Pump, Techland and the "Ministy of Sound"...for COPYRIGHT violations.

As to the relevant bit - section one, paragraph one, subsection a:
>> 1)A person is guilty of an offence if— >> (a)he causes a computer to perform any function with intent to secure access to any program or data held in any computer [or to enable any such access to be secured] ;
>Believe it or not, law enforcement and intelligence agencies are permitted to do things ordinary citizens aren’t
Believe it or not, that's just partially true.
> (b)the access he intends to secure [F2, or to enable to be secured,] is unauthorised
If you're trying to access a news website it's pretty likely that your access is authorised.
Without subsection b, literally every use of a computer is computer misuse.
And that's the key difference here - restricted by owner.
