Comma before "or" or not? [closed]

"Every student can learn, just not on the same day or the same way." – George Evans

From old technology – i.e., a source reference book – it should read "Every student can learn, just not on the same day or the same way." - George Evans

This is correct as 'not applies to both parts of the conjunction.

However, I see that there are many, many examples picked up by a search have added the comma after day. Who do you trust?
