Multiple people have said that she was brave, and that it was the 'right' choice, and one poster has essentially said there is no value in life, with comments such as "But why should she [live]? You can't regret missing something after you're dead," implying that killing oneself is a zero-regret situation.
In this context, it has been a mere four years (that's really no time at all with such a major loss) and I'm not aware of what therapy or medication she tried, but who knows how intensive it was.
Should someone who has depression for four years be allowed to pay a company to kill them, if they feel they haven't improved? Maybe a woman with PND that doesn't seem to be improving, after four years? And if not, why not?
Regardless - praising suicide as brave, the right choice, the only choice, ending her suffering etc, and publicising it as a tragic positive decision, goes against everything that one is meant to say about suicide, as it glorifies it and contributes to social contagion - meaning that it will contribute to more people attempting suicide.
Of course, if you think depressed people killing themselves is a brave thing, then I guess you'd be fine with that!
