I know Musk is widely disliked, but there will never be a shortage of talented engineers wanting to work with him, on interesting challenges, for very high compensation.
But how many talented engineers want to work with him, on interesting challenges, for very low compensation. Because historically with his other companies that's what he offers.
Yet people take those jobs at the other companies. Whatever he wants in his employees, recruiters will offer the lowest it takes to hire them, just like anywhere else.
I wouldn't exactly call an aging social media company from the 2010s "extreme and/or world relevant."
People still dream about spaceflight. It's something you can work on that feels like it matters. Skimming ad revenue off of millions of humans collectively trolling each other 280 characters at a time just doesn't capture the imagination in quite the same way, y'know?
This is exactly how he runs things at Tesla and SpaceX. Class A players are well compensated and love working on challenges that are extreme and/or world relevant. They live and breath what they do.
If you're that type of player, Musk will respect you and your opinion.
