I don't think he took an L at all. He now has successfully built, and sold a company. While being a dev at Google is somewhat elite, the number of people who have executed a successful sale is a tiny fraction of the number of FANG devs (or whatever we're calling FANG now).
There is a very high probability he gets offered a CEO position at some company that is looking for an exit path. That type of thing will usually come with a nice salary and a minimum 7 figure payout on exit.
As of this specific date, his bank account might be slightly lower than had he stayed at Google. 5 years from now it will almost certainly be significantly higher, and if it is not, it is more likely because he chose a path that he preferred.
