Docker hub probably makes no money. We pay monthly for it, but could easily switch to AWS ECR at this point with a cheaper monthly price. The Hub is nice in that it essentially has unlimited storage, but I suspect this might be an internal struggle for the company. We have no reason to go in and clean up 2 year old images that are 1GB each. We generate images on each commit - trying to do as much as DIFF reductions as possible, but if we change package.json - boom, puppeteer + all over again. And that's quite often.

But if they're using a deduplicating storage backend, they can shrink down the actual storage on disk across all customers to something quite reasonable.

That only works if Dockerfiles are layered in such a way to maximize caching (many are not and naively pack many changes into a single layer). Yes there are block-level dedupes but that's a transparent feature of most storage systems and not a competitive distinguisher of Hub vs ECR/ACR/Quay.

I believe the person you replied to was commenting on the advantages to Docker, not the customer, and how (blocklevel is what I inferred) dedupe makes the quantity digestible to Docker's pocketbook.
