Part of the issue the article notes is: once you start with Google (or any large, interconnected service ecosystem), there's quite a bit of activation-energy cost to leaving it.

Consider Drive as an example. You can download the entire contents of your Drive at any time. Where do you upload it to? How many services will provide a clean and easy way to import all Drive documents? Will they maintain folder hierarchy? Individual files in Drive can also be shared with zero, a few, or all users with a given URL---can your new collaborative document editing tool be set up to manage that state? Is it automatable, or something you'll have to set up by hand for 10s - 100s - 1000s of documents?

This is the kind of thing an enterprise can pay someone to sort out, but individual users really have to care about leaving a service family (that one assumes at some point in the past they were already happy with the privacy / security tradeoff) to invest the time and effort to do so without data or functionality loss.

I didn't "leave". I didn't "enter" the Google ecosystem.

Based on the article title ("Why no one really quits Google or Facebook"), your experience doesn't align with the scenario the article is talking about; it's scoped to people who already adopted these service ecosystems.
