As for Musk, he’s likely one of Putin’s assets too - he’s praised Putin repeatedly, he’s said he thinks Ukraine should just fork over their territory to Russia, and earlier in the war he personally ordered Starlink service cut to sabotage a Ukrainian drone mission using it for navigation.
My conclusion from these openly available bits of info:
Every bit of disruption their activities cause the US, the collapse in US science research, all the deaths they are causing, are intentional.
