Yeah. I did, so I got it. (I was technically a SWE but I mostly did product stuff. A bit of it went over my head.)
I also worked at Yahoo, so I can compare what you said to "big internet companies" as well. The dedicated hardware thing can be a nightmare. Using open source stuff internally can be a nightmare too.
I tried to only use names that were commonly known infrastructure components at Google, so I don't think this is really an issue.
I've searched for each of the internal projects (i.e. "google blobstore") and if there were no reasonable results, I've removed the references. All the others should be well known, so I've left them.

This is a problem everywhere big, and I agree one million percent.
