You should read what I wrote more carefully, nowhere did I claim that monopolies make better products.
Whilst that is doubtless true, that does not make anything better for customers.
If a company’s customers solely use their product, and not a mix of products, it’s much easier for the company to support and build new features for their customers. This is just a fact of reality, and one benefit of customers limiting the number of products they use.
Pointing out beneficial properties of consolidation and specialization doesn’t mean I support monopolies—I absolutely don’t.
