This is the kind of response I expect on Reddit not here. To me it is indicative of being influenced more by personal bias than truth and reason.
To answer your point though, Zubrin does not and never has worked for any of Musk's companies. Watson did work at SpaceX 8 years ago, but works somewhere else now so he has nothing to lose or gain from Musk.
And here is an account of a top NASA engineering official's interactions with Musk who also has never worked for Musk.
> He dispatched one of his lieutenants, Liam Sarsfield, then a high-ranking NASA official in the office of the chief engineer, to California to see whether the company was for real or just another failure in waiting.
Most of all, he was impressed with Musk, who was surprisingly fluent in rocket engineering and understood the science of propulsion and engine design. Musk was intense, preternaturally focused, and extremely determined. “This was not the kind of guy who was going to accept failure,” Sarsfield remembered thinking.
Throughout the day, as Musk showed off mockups of the Falcon 1 and Falcon 5, the engine designs, and plans to build a spacecraft capable of flying humans, Musk peppered Sarsfield with questions. He wanted to know what was going on within NASA. And how a company like his would be perceived. He asked tons of highly technical questions, including a detailed discussion about “base heating,” the heat radiating out from the exhaust going back up into the rocket’s engine compartment—a particular problem with rockets that have clusters of engines next to one another, as Musk was planning to build.
Now that he had a friend inside of NASA, Musk kept up with the questions in the weeks after Sarsfield’s visit, firing off “a nonstop torrent of e-mails” and texts, Sarsfield said. Musk jokingly warned that texting was a “core competency.” “He sends texts in a constant flow,” Sarsfield recalled. “I found him to be consumed by whatever was in front of him and anxious to solve problems. This, combined with a tendency to work eighteen hours a day, is a sign of someone driven to succeed.” Musk was particularly interested in the docking adapter of the International Space Station, the port where the spacecraft his team was designing would dock. He wanted to know the dimensions, the locking pin design, even the bolt pattern of the hatch. The more documents Sarsfield sent, the more questions Musk had.
“I really enjoyed the way he would pore over problems anxious to absorb every detail. To my mind, someone that clearly committed deserves all the support and help you can give him.”
