Who hacked 23andMe for our DNA – and why?

The intent is rather irrelevant.

DNA and whole-life outcomes have been an extremely contentious conversation, but one that's worth having, and any actor with more data is going to be able to make more fruitful insights.

A person (or, let's be honest here, nation state) with a large collection of DNA sequences tied to real-life persons has two major advantages:

1. They can draw statistical correlations between what individual genes and gene clusters are associated with economic performance and which are not.

2. They can identify genetic susceptibility/vulnerability. More benignly to things like chronic addiction, gambling, alcohol, nutrient deficiency, susceptibility to environmental effects etc. In a more conspiratorial direction it can form targeting data for weaponized/tailored bioweapons once those make their way onto the public stage.

The DNA part is completely relevant. If you consider it was a government that did the hacking.
