MS has a lot more money they “could” deploy if it were assured they would kill one of the main rivals between them and a position closer to monopoly in gaming. They are a bigger publisher than Sony is right now.
Sony trying the same “let’s burn money” tactic would be daft. Take Sony’s gaming profits and remove a lot of the PSN+ subscriptions and third party royalties revenue and see how they finance their AAAA first party blockbusters. Aside from trying to get promoted and thus having an incentive to sell smoke, they must realise that they stand little chance to get lots of PC gamers to buy event first party games from Sony’s own store let alone third party ones or PSN+ subs… a lot of people would still buy Sony’s first party games on Steam so Sony would lose even more.
The people that like this path the most and are applauding Sony and trying to cheer them on and accelerate even more are die hard PlayStation haters with a chip on their shoulders
