Evernote says that this is about ensuring their machine learning tech works correctly, but because sometimes things happen, human intervention is sometimes needed. “This is primarily to make sure that our machine learning technologies are working correctly, in order to surface the most relevant content and features to you. While our computer systems do a pretty good job, sometimes a limited amount of human review is simply unavoidable in order to make sure everything is working exactly as it should.”
The good news is that this policy has yet to go into effect as it is slated for the 23rd of January, 2017. This means that users can either choose to keep using the service knowing that there might be a time where Evernote employees may require access to their notes, or leave completely and bring their data with them.
