I think you’re presenting a terribly myopic viewpoint. A lot of companies make the process of interacting with them so painful if you don’t use their app, that you feel hounded, harassed, and yeah, in some cases, forced to use their app. Do you really think your idea here hasn’t been considered by the author? Of course it has, because like most older people (in their 30s and 40s), that’s how it always used to be. The author is complaining that the way it is today, it can be difficult or borderline impossible to do the very thing you seem confused about.
