Again, I personally don’t view these things as mutually exclusive. It’s a tech company and a car company. What’s so crazy about that? Apple is a phone manufacturing company and a software company. Amazon is a cloud provider, a video streaming company, a shipping and logistics company, and an online storefront. Companies can be more than one thing.

Also “subset” means a member of. If X is a subset of Y, then X is a member of Y. It would not be incorrect to say, “the list of Y includes X”
