With services you get a lot of lock-in/exclusives. Two examples are Discord and Netflix. I wouldn't say you have much of a choice if you want to join a popular place to chat or if you want to watch Stranger Things. The user experience doesn't matter so much if there's no other way to do something. This is what I think the person you were replying to means.

On that note, Google Sheets became popular because you can use it in your browser and because of Google Drive which is what locks you in. Sheets is much more open than my examples.
