Unless they are downsizing to 10-20 people, I don't see how that generates enough revenue to keep the lights on.

It's weird. Assuming Docker Enterprise was keeping the lights on, why would you sell your cash cow? Maybe the price was too good to turn down. But now Docker Inc finds itself in the same shoes as other companies trying to monetize open source without a platform.

If this means we'll get to pay for Docker on the desktop AND it'll get improvements, I'm all for it. But it's a tough situation nowadays (nobody expects to pay for most developer tools).

Docker Hub is hosted on AWS and Docker doesn't charge for egress. I wouldn't be too surprised if private registry revenue doesn't even cover AWS egress (even with huge discounts Docker likely has).

Other registries like Bintray or GitHub Registry charge $0.45—$0.50 per GB egress, while Docker Hub charges a much smaller flat fee.

yeah I know Hub has some revenue stream, but I'd be fairly surprised if it even covers the cloud bill they must get from all the free repo's.

From my experience most companies using private repos use their cloud provider's ones for the IAM integration.
