I agree, irks me some too, they make it sound oh so easy and it's bluddy not at all :|
Worse than that, they make it sound easy in interviews. The average reader is going to read that and not know any different, which further confirms the belief that anyone can immediately get citizenship just by getting married. That will influence public opinion, making many people think that it's too easy, which will in turn influence future government policy.
So no matter what they do to increase the difficulty, as long as people think that it's easy, and are (incorrectly) validated in their thinking by the media, it will continually be made more and more difficult.
Maybe we can get Katy Perry to make multiple public statements about how she just wants to come to the UK to be with her husband, but it will take years of visas, tests, ever-increasing fees, and ongoing stress before it's permanent.
