No, their business is consumer electronics. Those consumer devices contain (and are built with) tech, but the tech is not the product itself. This is in comparison with MS, which for the most part sells tech.
I mean, Apple is at the point where they're designing multiple custom chips: a general-purpose CPU (A12X), a SiP (S4) an ARM SoC (T2), a wireless-focused SoC (W3), and an audio-focused SoC (H1).
Is Intel not a "mega tech company"? They have 75% the market cap of Microsoft, and virtually all of their revenue is from producing silicon.
Ironically this is exactly the point you miss - Intel's business it to produce and sells silicone. Intel's cohorts are AMD, ARM and NVIDIA, and they are all technology companies who's business is the development and sell of technology.
Apple produces consumer electronics, and though in many cases it also designs and produces some internal technology components, their business is not in any way dependent on selling that tech in itself. In fact it's arguable that the main influence on whether an apple component is developed in house or outsourced is economical/logistical and not tech based at all. Apple's cohorts are Sony, Samsung, LG etc, all consumer electronics providers.
A better word to use is tools. Microsoft and Apple both sell tools but Apple tools are a fashionable consumer tool sold at retail, and Microsoft are business tools sold to enterprise.
Google and Facebook give away free tools in exchange for attention.
Netflix more correctly fits your example, they dont create public tools used to accomplish something else, their tools are built internally. Same with Uber.
Netflix? Tool for easier to content delivery. Uber? Transportation tool.
Everything is a tool if you reduce it far enough.
With Netflix I cant buy their tool and use it to host video for my friends. I cant buy or lease Uber tech to start my own taxi network.
