amazon does have a lot of revenue, but it doesn't have the extreme margins that companies like google and facebook have. they can't just throw money at problems the same way. amazon has similar margins to walmart, and only just exceeded the latter's revenue in 2020. would anyone argue walmart is the more innovative company?
