AWS data transfer cost within the same region, but belonging to different accounts?

It seems like data transfer costs from S3->EC2, or EC2->EC2, is free if they are in the same AWS region.

S3 price caveat:

You pay for all bandwidth into and out of Amazon S3, except for the following:

• Data transferred out to an Amazon Elastic Compute Cloud (Amazon EC2) instance, when the instance is in the same AWS Region as the S3 bucket.

EC2 price caveat:

Data transferred between Amazon EC2 [instances]... in the same Availability Zone is free.

Data transferred between Amazon S3... and Amazon EC2 instances in the same AWS Region is free.

Source: https://aws.amazon.com/ec2/pricing/on-demand/

Would this free data transfer pricing apply if the receiving EC2 instance belongs to another company in a separate AWS account? For example:

If Company A sends data from the EC2 EBS, or from S3, to Company B, is the data transfer costs still free? Or would Company A have to pay, and if so, what would the cost be?

Data transferred “in” to and “out” from public or Elastic IPv4 address is charged at $0.01/GB in each direction.

So, depend on traffic flow.
