it's very correct.
Microsoft windows and office only make money with kickbacks to govt buyers. see the documentary on Microsoft and EU. lots of money is moving under tables.
azure is a joke that mostly gets sales based on price for people who need to buy a cloud just because. in this regard they are a walking corpse like ibm was in the 90s.
then the money came from xbox, which they tried to kill several times and only got market share because they sold at loss early just because that's what they do without even thinking. Salesforce, and LinkedIn, which they bought after they were monopolies already (and owners only sold exactly because of the fear of saying no, which the article paints very well) and couldn't run to the ground no matter how bad and abusive it got. and lately openai related stock memes despite being the least protected player (as in no hand in chip design).
what exactly paints the article as wrong? they just got a few luck hits on the way down.
