I have no love for big corps, but they're likely just reading the writing on the wall. they have to deal with retribution for the next 4-12 years and they have no interest becoming the rebels. I'm kinda impressed they stepped away at all other than it probably was money spent for nothing.
IBM supported the Nazis, and if they're the only tech giant not fighting musk they're going to get the kickbacks. Corps dont do "writing on the wall" anymore, they chase money, which may look similar but the goals are different.
