I will without a doubt leave Evernote after many years of premium account if this policy is implemented indeed. That is totally outrageous. If you want to verify accuracy, then ask volunteers instead. Also, why don't you spend time and energy in bettering your existing offerings or by innovating on new features (Like making your IOS less buggy not giving up on Skitch, bettering penultimate app for hand notes and text recognition, better integrations, like with Alexa lists for example, etc.)
OneNote is quite a good contender, so the switch won't be so difficult.
