It was after a year or so of usage that I realized that Wire does not provide any way to export or save chats outside of its application (it has a backup option to backup from and restore back to Wire). Wire also seems to store images on its servers and those images won’t be available if you save a backup and restore from it. The backup formats are platform/OS specific. Losing images but having just text alone was a big loss for me.
For all practical purposes from a basic end user’s point of view, Wire can be considered as proprietary and closed as Instagram or FB Messenger.
