But also they've segmented away business users to Red Pro, Gold and Ultrastar drives for a few years, so I'd imagine sales of Reds today mostly fall in that range so more motivation to shave costs. With SSD pricing these days, <2TB hard drives just don't really make sense, but also I'm guessing very few home users need/want more than 8TB of storage.
There's a large market for "power" users who want high specs on paper but don't need them. The market response is to fake the specs or make compromising tradeoffs in lesser known specs.
Often it works out fine and everyone is happy, but sometimes a bunch of customer use cases get broken.
