If you don't invest in companies that don't release hardware unit sales, your options are rather limited since the following companies don't provide that data either:

Dell, HP, Microsoft, Amazon, Google, Samsung, LG... etc etc

Red Flags everywhere

That's interesting how publicly traded companies are not required to release these numbers. I wonder if that's always been the case?

Why would it not be the case? The important thing to report to investors is the financials. The last thing you want to do as a company is advertise to your competitors exactly which of your products are failing and which are succeeding. Also, it would be insane if companies had to report "Unit sales" do they have to report iPhone 7/8/9/X? Or 7/8/9/X + different colours? How about X vs X+? Do you need to know iPhone X+ White 64GB sales?
