Regardless of what you call it, any market vertical that you can define with less than 5 genuine competitors invariably winds up being anti-consumer and needs to get broken up.
Apple is the focus here, but Google is no better and neither is Microsoft. Search, messaging, email, video--all of these are easily definable market verticals.
All of these need to get broken up until we have at least a half-dozen competing companies in those spaces.
This isn't limited to tech. Grocery store chains, industrial suppliers, financial companies, etc. all need to get smacked with the same breakup stick--especially if we want not just to not only stomp out anti-consumer behavior but also to have genuine supply chain resilience.
