This is kind of sad. I'm probably missing context here, but surely it's not necessary to rush out of a good working relationship with a good mentor. The most important things you'll learn from a good mentor can't be learned in a rush (like prioritization, project management, how to be a good mentor...).
In any case, I would replace 'jump ship' with 'pay it forward.'

Yeah, don’t do this. Great way to ruin your reputation as a dollar chaser and be exiled to the consulting wastelands. Burning bridges takes minutes. Building them takes years.
A great mentor won’t waste their time on someone cynically using their time to cash out at Meta. Such a person can just get a CS degree and launch into Amazon for that.
Big Tech are just the IT enterprises of the modern day. It’s not where the action is and that experience is not so hot on the CV when it comes to early stage development.
If you find a great mentor, do everything you can to learn quickly then jump ship to big tech and cash in.
