Yeah, I think a key point is that Salvatore Sanfilippo, the original developer, maintainer and principle contributor[1] for 11 years, was not a founder of Redis Labs. He joined as an employee in 2015 but resigned in 2020. Perhaps he has equity in Redis Labs, but it's not clear he stands to profit at all from this switch.
