Space X has an entire department that does nothing except to keep musk from meddling in projects.

It's still a company where egon murks had his hands in, so no warranty is given that ANY department there achieves anything they "claim" to do, want, can, should, would but blame others to sabotage or such, same with that department. period. There was murks in it once, you never now when some shit he pooped there would hit the fan or the oxygen generator.

Do you want a "claiming to provide oxygen" system on mars or would you rather want the ACTUAL oxygen no matter who is in charge, claims to be or not but delivers it anyway?
