It got quite good exposure on the radio yesterday. Basically, as commentary states, it's not about allowing access to his account, it's the subsequent access to his friends that he didn't want to allow.
Of course, the other side of the coin is that if you are going to use your Facebook account to represent a brand (the party), then they should have some control over the brand.
The easy solution is for him to make a new Facebook account to use during the campaign that can be controlled by the party to make sure the message stays consistent.
It's much more likely to be a cultural issue than anything "weird". If you aren't used to having your picture taken as a culture, having strangers (ie. tourists) snapping shots of you and your loved ones can be intrusive.
