Some clarification I got from Daniel in a private conversation, since
I was confused about what the money was paying for exactly:

We're paying 75K USD for the bandwidth to transfer data from the
GitLab cloud instance. i.e., for viewing the https site, for
cloning/updating git repos, and for downloading CI artifacts/images to
the testing machines (AFAIU).

I was not aware that we were being charged for anything wrt GitLab
hosting yet (and neither was anyone on my team at Intel that I've
asked). This... kind of needs to be communicated.

A consistent concern put forth when we were discussing switching to
GitLab and building CI was... how do we pay for it. It felt like that
concern was always handwaved away. I heard many times that if we
needed more runners that we could just ask Google to spin up a few
more. If we needed testing machines they'd be donated. No one
mentioned that all the while we were paying for bandwidth... Perhaps
people building the CI would make different decisions about its
structure if they knew it was going to wipe out the bank account.

What percentage of the bandwidth is consumed by transferring CI
images, etc? Wouldn't 75K USD would be enough to buy all the testing
machines we need and host them within Google or wherever so we don't
need to pay for huge amounts of bandwidth?

I understand that self-hosting was attractive so that we didn't find
ourselves on the SourceForge-equivalent hosting platform of 2022, but
is that risk real enough to justify spending 75K+ per year? If we were
hosted on gitlab.com or github.com, we wouldn't be paying for
transferring CI images to CI test machines, etc, would we?

So what do we do now? Have we painted ourselves into a corner?
