What does HackerNews think of nomulus?
Top-level domain name registry service on Google App Engine
For a company like Google that pays top tier salary, there is no way that selling domains (especially not in bulk, their targets are mostly consumers and businesses, domain traders use other services) make enough money. If you take a look at the commiters on https://github.com/google/nomulus
That's at least 10 engineers maintaining one component. Add in SRE and product executives, you are looking at expenses in the two digit millions minimum.
The decision is definitely short sighted but somebody high up no longer wants it as a loss leader.
The source "googleblog.com" next to the title on HN is clear enough. It's a company that open sources a project on github (https://github.com/google/nomulus). I don't think the announcement is disguised, spinned or misleading.
My downvote as off-topic came because it didn't address the announcement itself. To be honest I had the impression you read the title only, not the announcement itself.
That said I think the title techcrunch chose is clearer "Google open sources the code that powers its domain registry"
