That makes very little sense to me. When your Subversion server is gone, you're hosed. When your Git forge is down, you take any old SSH shell account anywhere, push and keep working.
So there is more to lose than just the service being unreliable.
As a person he's either a poser or a neo-nazi. As a government agent he's responsible for many deaths and as of yet untold harm. Tesla was one of the earliest EV manufacturers, but these days they're overpriced and will be remembered for panel gaps and being destroyed by a car wash. SpaceX has done a lot for that sector, but will mostly be remembered as the company that fucked astrophotography with 10s of thousands of satellites. And Twitter has been dragged into irrelevance so badly it was being called a "reverse startup." Neuralink seems to be going nowhere...
Where's the benefit?
