It’s not a “messy” area at all. It’s just a misunderstanding of the law. If what you’re saying is truly “illegal”, no court of law has found it so since Office was introduced over 30 years ago.
What’s more likely, that “bundling” as you define it is illegal and has never been prosecuted in over 3 decades or that you don’t understand the law?
It's far more likely I don't understand the law, but the discussion had turned from bundling to monopoly and antitrust questions, and I stand by my statements, as confirmed in the source I linked.
