But again, others could make these things. Google, Zoho, etc have.

If a company is winning simply because they’re able to prevent meaningful competition (such as Google buying up default search) that’s a failure of regulators.

If a company is winning because people like their product better and they’ve spent a lot in R&D to make it better so it would cost a lot to catch up to, and it has several competitors who just might not be as good, that’s exactly what you hope for.
