I am not saying whether the camera behavior is incompetence or malice, I am just saying that "download your data" features rarely give you all your data, both for malicious reasons (in the case of Facebook) as well as technical reasons (some data in raw form might belong to multiple individuals so you can't just give them that raw version and need to write extra code to sanitize that data which might not have been done yet so until then you would be missing that data).
