Storj is not in business of making backup apps. They are providing storage services for developers.
Making an app is simple. You can build one it in a week. Making a reliable app with great user experience and supporting it — is ridiculously difficult and requires completely different skillset. It’s a job for a separate company. Those companies already exist and are well established.
It makes no sense for storj to waste time on that.
This thread is going in circles.
