It's a multi-layered satirical joke. The 'absurd' aspect is the flipping of 'taking over a library' versus starting one, which is amusing given that the motivations of state-sponsored bad actors are to poison and/or control the hard work of others. They themselves would end up doing the hard work they've undermined. Further satirical layers are added by the prospect of those bad actors producing 'good' software instead of 'evil', and providing funding that they've historically been reluctant to cough up.

Of course, as the old saying goes, explaining a joke is like dissecting a frog: nobody laughs and a frog dies.
