I get what you’re saying, but I think what you’re describing as the “realness” of a company is just the sustainability of its competitive advantage. Which is a good metric to understand their long term financial position and susceptibility to market changes and layoffs. Others are pointing out that yes MS and Amazon make physical things, but we all know those aren’t their core business - that’s beside the point.
Tech companies are largely “interface” providers - they simplify the interface between a human and some other thing. Twitter simplifies the interface between one human and all other humans on Twitter. Microsoft enhances the interface between one human and other humans within a company. Amazon simplifies the interface between humans and retail goods, and AWS simplifies the interface between humans and scalable compute and storage.
Apple simplifies the interface between humans and personal compute, which is the entry point to all of the above (although the relationship with Microsoft is obviously more complex than that). So Apple is just further up the tech value chain, where transient effects are softened and delayed, and where competitive advantage is less easily displaced. Twitter is really only protected by network effects. Microsoft is protected by lots of UI/UX implementation moat and strong vendor lock in. Amazon is protected by others’ ability to scale physical logistics, AWS by backend and interface development and also lock-in. Apple is protected by all of the above plus hardware engineering, and the hardware is an especially difficult one to catch up with or copy.
