5 occurrences of "Microsoft" in the article body vs 9 "OpenAI".
To make my point clear; this weirdness was definitely caused by the OpenAI board deviating from everybody's plans, including a member of the board themselves.
From there, Microsoft strategically reacted to a black swan event. From MS's pov, this was a zero-day attack that would manifest itself in 2-5 years, Google vs FTC style, and the mitigation strategy was providing the appearance of welcome arms++ to the tyranny of a board that makes kneejerk decisions, and having those open arms be rejected by the (natural) out-pour of sentiment.
The end result is identical, and Microsoft turned a zero-day attack into an irrefutable defense for any future FTC lawsuit.
