“nurlan” asked in Slack:
What does “control your data” in the definition of your service mean?
When you post on facebook or twitter, your content is stored in databases controlled by the companies that manage those services. If you want to move your posts or photos to another service, the services you keep your data with do not provide a simple migration path. If you are concerned about engineers at facebook or twitter reading your messages, you have no option for privacy.
This is not controlling your data.
When you control your data, you control where it is stored, how it is stored, who can read it, and what applications can access it. You are not locked into a particular provider and the software that you use revolves around your data, not the other way around.
