In 2016 Saudi Arabia was armed to the teeth by the Trump (Administration #1) to launch a huge multibillion invasion of the Yemen, bombing, cutting off food supplies, as a tactic of war, causing a famine which left over 370k people dead.

In addition the Saudi's Armed the gnocidal Jajaweed/RSF (again with US weaponry) to fight in Yemen, the same RSF who have now creating mayhem and collapse in the Sudan.

The question is, given these encyclopaedic statements about corporate responsibility, for what exactly do they count for? when Microsoft is happy to engage with this regime which:

which arms and supplies a group known to practice mass genocide/ janjaweed /rsf sponsored by Saudis * a government which practices mass starvation and invasions of it neighbour * is know for torturing and dismembering dissidents alive

What do all those links mean if it allows this?

To answer your question, the links mean that it has achieved compliance with the laws of the governments of the other countries it operates in, no more than that.

Your geopolitical insinuation is interestingly monofaceted, however. Ignoring the many domestic pressures at the time which are relevant (such as vote share in arms-producing districts), the 2016 action by the US (1) acted as a small hedge against any gains in regional power by China, Egypt, France, Germany, India, Iran, Israel, Jordan, Oman, Russia, Turkey or the United Kingdom (such as market share or diplomatic point-scoring) while (2) simultaneously implying to MBS that, in the short term (2-5 years), he was on his own with respect to Iran and (3) moderately reinforcing the carefully cultivated political aesthetic of U.S. impulsivity and violence.

All three of those modest goals were achieved and were later undermined by unforced errors elsewhere. Alternatively, one could consider that those goals were achieved to build up a reserve of political capital that could be expended to permit the unforced errors elsewhere.

Its a bit late for Norway wealth fund to be concerned about human rights in tech companies dealings. Potentially damaging to Microsoft exposing how many children were __potentially__ killed or tortured with aid of Azure datacentres. That could damage Microsoft and potentially the wealth fund!
