Whether these companies account for their own use of infrastructure as cloud might be the difference. Do these companies consider all of their own products running on their infrastructure as cloud and therefore consider expenses for those as cloud revenue (and cloud expenses)? Or their kind of separate products like Github, Waymo, etc. Amazon's non-cloud products probably use much much less data center infrastructure than Microsoft and especially Google.
