It is actually pretty easy to answer questions like this by searching the web. Below, I have done some work for you.

First, though, gotta say that the most generous reading of your arguments is that you are philosophically defeatist and suffer from "the perfect is the enemy of the good"---- why do anything except the one final action that will solve it for good? If that is your attitude, why bother posting on a forum? Why bother doing anything?? To learn about the broader strategy, you could try Boycott, Divestment and Sanctions - Wikipedia. Nobody is arguing that MS should be targeted instead of promoting governments to sanction and remove the subsidies that keep it afloat. But Brian Eno thinks he has more sway with MS than with the US government, so that's what he's throwing his back into.

'Microsoft Powers This Genocide': Firm Fires Pro-Palestine Disruptors of 50th Anniversary Celebration | Common Dreams

The protests come a few months after the publication of an investigation by The Associated Press which found that Israel's use of Microsoft and OpenAI technology "skyrocketed" following Hamas' October 7, 2023 attack on Israel, which prompted Israel's deadly campaign on the Gaza Strip. Multiple human rights groups have said Israel is guilty of committing genocide or "acts of genocide."

Specifically, the investigation found that artificial intelligence "models from Microsoft and OpenAI had been used as part of an Israeli military program to select bombing targets during the recent wars in Gaza and Lebanon."

Ex-Microsoft employees expose company's role in Gaza genocide, quoting Hossam Nasr:

there needs to be a focus on Microsoft's actual business practices as they affect Palestinians in Palestine and as they directly contribute to the genocide and the horrible scenes that we were seeing coming out of Gaza.

And two, the need for a strategy to put pressure on executives rather than trying to appeal to the humanity and moral character of these executives.

We started researching Microsoft's complicity in the genocide, trying to find out exactly the target and strategy for this campaign.

We then formally launched No Azure for Apartheid in May 2024, with four main demands: IOF (Israeli Occupation Forces) off Azure, ending all sales of any Azure cloud and AI services to the Israeli military and government.

Two, disclose all the ties between Microsoft and the Israeli military-industrial complex, the Israeli government and the Israeli military.

Three, calling for a permanent and immediate ceasefire to honour an earlier petition signed by over 1,000 employees.

And lastly, to protect employees and uphold free speech by ending the discrimination and the double standards against Arab, Muslim, Palestinian and allied employees.

Microsoft must be held accountable for its complicity in Gaza genocide, rights group says – Middle East Monitor

According to human rights and media reports, since the beginning of the ongoing war on Gaza in October 2023, Microsoft has provided direct technical support to the Israeli occupation army worth at least $10 million through its Azure cloud platform.

Reports revealed that Microsoft’s support included data management services, the development of targeting systems, advancements in surveillance technologies and the provision of cutting-edge AI tools. These include ‘Lavender’, an AI-powered system designed to identify bombing targets, which has faced accusations of being linked to the deaths of thousands of civilians in Gaza.

Furthermore, the reports accuse Microsoft of supplying biometric surveillance technologies to track Palestinians. This comes as the death toll has surpassed 50,800 people, including more than 18,000 children, according to Gaza’s Ministry of Health.

In a statement, Skyline asserted that Microsoft’s continued support of Israel violates the UN Guiding Principles on Business and Human Rights. The organisation urged the company to transparently disclose the nature of its relationship with the Israeli occupation and to terminate all forms of cooperation linked to military activities that breach international law and human rights.
