He's doing a suck job of it. The things he's gutting are pennies towards his dark-souled oligarch masters. Cutting small government projects like the NEA, PBS or like FOSS grants is only used as an appeal to fiscal responsibility conservatives that aren't willing to cut into old-people benefits like Social Security and military sacred cows. Not because gutting tiny projects does anything useful, rather it gives the vibe that representatives are doing something.

This is an appeal to the imbicile MAGA though the tech bros might have specific FOSS projects that compete with their own commercial offerings. Not enough to cut all FOSS grants, though.
