Re: I may be wrong
You forget that GCHQ, like most agencies, is not a simple creature with a single goal.
What they should be doing is protecting the UK: that means defence, business and private lives, as they are all inter-related.
On one hand that means stopping The Bad Guys(tm) from having access, and that means encouraging properly used encryption to make sure that information goes where it should and not in to the wrong hands. On the other hand it means having to break encryption to spy or assist the police for what should be the same goal, and there is an obvious conflict of interests there.
Most will realise that both goals are justified, but given the evidence of past
lying and political machinations bending of the rules, there is a serious mistrust of either goal. This is made so much worse by the clueless fuckwits calibre of politician we seem to get in charge of the situation.
