To me that disclaimer sounds rather like those disclaimers on dietary supplements. They have to write that the supplement isn't medicine and might not work but the whole product packaging and marketing implies that it will work just like medicine. "Yeah, yeah, crypto cat is software and no software is perfect. But ... that's just a stupid disclaimer. Use cryptocat anyways, guys."
