I can see why that article appeals to you, Roussette, but I find it a bit overblown. 
This battle was already won by Meghan in the U.K.’s courts
At first instance, yes, but unfortunately for Meghan as part of a fair judicial system there are two tiers of appeal to every case.
Now the paper has sought to appeal her victory and paint her as calculating, manipulative, and even diabolical
Her admission that she mislead the court has rather helped that view, don’t you think?
This is an attempt by The Mail on Sunday to undo the right to privacy she has already won
Well, they’ve appealed, which they are perfectly entitled to do.
A letter she worried would be leaked anyway
Yes, she certainly contemplated would be leaked anyway. Worried? Given how happy she felt having drafted those “words she could never say in public” and how unconcerned she was when her friends leaked it, apparently behind her back, other views might be possible on this.
Imagine knowing that your every move, even the most intimate communications with your family members, could be weaponized against you
Yes, imagine that. Prince Charles and Camilla (tampongate) and William, Kate and Harry (private voicemails routinely hacked into and listened to) might how some idea how that feels, too.
