Not exactly. It sort of depends on your interpretation of events and times.
When the original "Google" turned into Alphabet to split the core Google stuff like search and advertising from all the other side stuff like CapitalG, Waymo, etc. So the entire "Google" corporation as it was, turned into Alphabet. The new Alphabet motto is "Do the right thing."
The "new" Google subsidiary formed under Alphabet still used the phrase in its Code of Conduct. In 2018 they removed it from the preface, but it's still the last thing mentioned in the Code of Conduct.
