No no, there isn't no 'main problem' as this hasn't been news in DK (besides the one article on BT's website) Nothing special. Probably because people can think for themselves. Thankfully
ADDED:
I would like to add something I think is quite relevant when I read your post:
Remember that the statements of Trine Willeman are eight years old! They are from her book back from 2008. So almost a decade old. So I don't think we can use them, especially not now in 2014!
Since 2008, every poll Frederik and Mary has switched to be number 1 and 2 in the popularity measurements. The latest Gallup survey back from the beginning of this summer showed Mary and Frederik were the two members of our royal family the Danes think represented Denmark the best (The Queen just behind them) Back in the spring (at Frederik's birthday) another poll showed that 8/10 want Frederik as King now or within the next ten years.
This Gallup survey from last year shows that 77% of Danes think Frederiks is ready to become our King today:

So why on earth the Australian guy chose to use those old statements by the famous TW? Well, maybe because it was the only thing he could find?
And while Mary certainly has had a big influence on Frederik, love
does wonders and I think she gives him a lot of security (said by himself she is his biggest supporter) Frederik himself certainly has a huge role in his own development.
