I think they have made a mistake. Back in the day, I went to church regularly to be choirboy, and later on to ensure my daughter got into the local church school (by singing in the church choir - so I feel like I gave enough to the church to justify it, even if I'm a non-believer!). The nice thing about CofE was that it was quite a casual church. A nice community where you could go for a sing or a pray, but there was no coercion and non-believers were as welcome as believers, usually in the hope that at some point they might change their mind.
When our local vicar retired and we got a new pair of vicars (married), suddenly advertising for Alpha courses started to spring up. The services became evangelical in nature and much more dogmatic. They started a campaign with the Diocese of Guildford to get rid of the head teacher of 18 years and made up accusations of breaching child protection guidelines and misconduct (tribunal found him innocent of all charges and that that the "Good Shepherd Trust" was guilty of wasting their time).
Then you have things like the appalling way that Richard Coles was treated when his partner was dying.
The Church of England is quietly destroying itself by being quite nasty and losing sight of what it used to be.
