What if the service costs more to deliver than the market is willing to pay (e.g., search engines and social media)? I think it's reasonable to have advertising-supported services, it just needs to be clear up front. I don't mind dropping Netflix, Hulu, or other streaming services for Blu-Ray ripping and Plex if it gets too expensive, even with ads.
I don't think G-Suite customers are excluded from Google's ad tracking network. Microsoft enterprise? Neither. All you can ask if that they don't show you ads. And even that is temporary
Without regulation, you have no protections against these corporate actions. If you’re expecting or relying on corporations to act in good faith, you are going to be disappointed.
