I generally agree, but it also does feel like just an extension of dogfooding. If you work for a company that has a product that solves a certain business need, it generally makes sense that you wouldn't hire a different company to solve that need. Obviously in this case the reasonable response is that Teams and WebEx are worse products and MS and Cisco haven't shown much inclination to fixing that, but that's more the fault of the company's bad products more than anything about the internals.
