I wouldn't think so. In a society so rife with obvious scams everywhere you look, at every level in public and private sector orgs, it would be patently idiotic to trash your own career on account of a dishonest restaurant review operation.
I wish we lived in a world where such bravery were meaningfully valued, but we don't. For any might-be whistleblowers, this reality has been made painfully clear in the time since the Snowden leaks nearly a decade ago, during which nothing has changed.
