Yes, Microsoft would like to dominate the console market and leverage that to push people into the Microsoft PC ecosystem.

Since they've done poorly with the "make a better console with games people want" strategy, they've pivoted to their strength, which is a huge pile of money that they can deploy to try and get control of the content which Sony can't match.

They'll say what they need to in order to get this approved, but long term they'll absolutely leverage their ownership to achieve their goals.
