Isn't it the opposite? If you're at a FIRE point, there's no downside to trying to do possibly-job-ending things at your workplace. You're ready to leave anyway.

And anyone who's been at Google for a few years, even not at L5, will have no trouble finding a job elsewhere that pays as much (or more - last time I had a Google offer they flatly refused to match fintech salaries). Just make sure your name doesn't get into stories like this and resign a bit early if it seems like you're losing.
