Two more facts tilt in favor of Brian Acton here:

1. Encryption made WhatsApp inherently more resistant to being polluted by Facebook. They still get access to highly sensitive metadata about contacts and groups, but they can't do the kind of things they did to rape and pillage Instagram.

2. He took his money and his free time, and has invested heavily in supporting Signal. While Meta lets WhatsApp rot and slowly becomes Yahoo, Signal is solidly on its way to become the OpenStreetMap/Internet Archive/Wikipedia of social communication apps.
