I mean not technically… those products use a separent kernel that has its own development path away from the Linux kernel. Linux is just a compatible Unix kernel but I wouldn’t classify it as a Unix operating system since it diverges into its own thing.
Android still uses the Linux kernel not some piece of code that they developed and not some commercial Unix product
GNU is a recursive acronym for “GNU’s Not Unix!”,[6][12] chosen because GNU’s design is Unix-like, but differs from Unix by being free software and containing no Unix code.[6][13][14] Stallman chose the name by using various plays on words, including the song The Gnu.[4]: 45:30
Isn’t that like claiming all Linux, Android and MacOS are just UNIX?

Not if they don’t share any heritage with Unix. Osx is the only one that fits the bill there.
