Giving you an option to only bulk egress is not the same either, since the most common scenario for egress would be operational day-to-day inter-network scenarios.

If there is an unreasonably high fee for exiting a provider's cloud, to any other network location, on an operational basis, it is actively discouraging exiting the provider's services creating a kind of price barrier that could be cost prohibitive for operational inter-networking.

Operational inter-networking, to me, encourages competition not discourages it.

For example, perhaps I want to use Microsoft Azure's Data Factory to move data from AWS S3 to Redshift. It is not possible as far as I know without egress from AWS to Microsoft's network, and then back again. But surely these clouds are connected with peering relationships making the cost of ingress/egress negligible, so why is this not allowed? That would allow users of the cloud to freely mix and match services from among many clouds.

The world I see today does not seem to encourage such competition.
