Many times I see people cite these statistics as if they are the actions of the company. However. 90% of those donations are from individuals that work for Microsoft and list Microsoft as an employer. It’s cited towards the bottom of the page. I think that this mostly tells us that there exists a decent number of politically active employees and that a large majority of those donate to democrats. The remaining 9% of the donations are PACs which would have their own disclosures. I couldn’t find reference on that page for which PACs Microsoft is donating too though and which party those PACs are donating to.
