This is concerning, it feels a bit tragedy-of-the-commons I suppose where having public tests are a valuable public good, thought I can't quite get the analogy straight in my head.

I have a personal theory that "tragedy of the commons" has a very specific meaning, and beyond this meaning it just adds confusion. This isn't your fault - it's an overused phrase.

I'd try to examine the root of your discomfort. Why does it make you feel bad? Avoid thinking about "big ideas" like the commons or the public good.

It was a joke.
