The clear dip in CS is what the rest of my comment is about. The point is that the entire premise of the original post, which claims CS enrollment is "flat" by cherry-picking a specific benchmark year and ignoring huge movement between that year and the present, is indeed "'misleading with data' at best", because CS enrollment is not "flat". If you pick an earlier or later year, you get different narratives.
The post then spends a bunch of time musing on why CS enrollment supposedly doesn't respond to economic incentives, even though responding to economic incentives, i.e. rising and falling together with tech booms and busts, is precisely what the data shows it doing.
