My money's on two possibilities. Either Mitsoda was proving to be too unsatisfying of a creative lead thanks to his "social anxiety" causing problems with production or just making it impossible for him to gel with his bosses and coworkers. Or he just wasn't woke and/or profit-oriented enough for Paradox's tastes. Either way, it's a good avenue to get rid of him and replace him with a weasely consultant who's clearly just there to make the project more in-line with Paradox's agenda. As such, expect it to be even more woke than it already is, and for it to feature more "creative solutions" to milking players for all that they are worth.
