Email is the paradigmatic example. You can export your mailbox and use `pine` if that's your jam. But in the real world, most users of Gmail will depend on at least one feature of Gmail that isn't easily replicable elsewhere.
I wonder what gmail's churn rate even is? It is surely staggeringly close to zero.
I wouldn’t be surprised if they have more churn via death (people, companies, abandoned projects) than any other single source.
At first I thought "email seems a good example of this: most people don't want to leave Google, I don't want to leave FastMail"... but then I remembered that I could just leave FastMail and take my email to Google. Which proves the upthread point about the open protocol being a safety net for users.
Can you talk about some examples of monopolised open protocols?
