Largely true but as a small aside, Google is still a company (within Alphabet). Alphabet is purely a corporate structure, and all branding still has Google on it. Whereas Facebook is now only a product, Meta is the company brand with its own logo and products named directly after it (like Meta Quest).

As a long time Linux user, I was amazed when the entire tech industry “invented” package management a couple of decades after Linux. Did you know Apple invented the idea of being able to install an app and all its dependencies, signed by a central authority? So much easier than any other OS before it!
