That's not what it says; with "70% of a couple hundred megabytes are copied around for no good reason" written in bold no less:
> That’s right! More than two thirds of the file on disk is taken by… bits of dubious value to the software product. > > Moreover, consider that these executable files fly around as container images, and/or are copied between VMs in the cloud, thousands of times per day! Every time, 70% of a couple hundred megabytes are copied around for no good reason and someone needs to pay ingress/egress networking costs for these file copies. That is quite some money being burned for no good reason!
