Just because you disagree with someone does not make it ok to dox them.
Is it "just disagreeing with them" or is it taking away privacy _from those publicly renouncing the right to privacy_, with goal of protecting the right to privacy of everyone else, who didn't renounce it, by pointing out the hipocrisy and that it actually is important, even to those who claim otherwise trying to take it from others?
Actually it does, and much more.
That's a bit simplified, isn't it? He's pointing out precisely that "doxing" the entire population of Denmark shouldn't be acceptable to her, and that she's literally not accepting herself being "doxxed." If it was about, I dunno, pizza toppings or school budgeting, then obviously the actions would have been different.
