Or anyone who can advertise lower outbound data costs.
Which is pretty much everyone else except GCP.
Why can't GCP advertise/provide lower outbound costs? Do they do something special with their networking that makes it substantially more expensive?
Beats me. They offer "Premium" (~0.12$/GB) and lately "Regular" (~0.8/GB) network tiers, and their interconnect service. I guess high cost of outbound networking helps locking in customers as well.
