I thought "Tragedy of the commons" referred to people over-harvesting limited resource in an unsustainable fashion knowing it is wrong because it wont matter if "just they" do it. And then everyone does it, and the resource dries up and everyone starves.

This would be inverse in the sense that there is no limited resource being depleted, but bad seeds being sown, choking the environment and making it unsustainable.

To me it seems like the same category of problem, but with the opposite kind of adversary and feedback loop, so I assumed it wasn't covered by that term.

But it's also very likely that this is just the sort of unproductive, needlessly detailed nitpicking which geeks are so very much famous for. I've been known to go down that road before :)
