If this letter would have started with, "I stayed at Google for 15 years even though I knew it was unethical. I'm a piece of shit. BUT I'm going to try and redeem myself..." then it would have been much better. Some kind of redemption arc.

The damage has already been done, man. You don't magically earn the moral high-ground for "quitting" after 15 years with an angry letter.
