I'm late chiming in here on this, but I didn't realize this thread existed until Evernote responded to my ticket on this very issue. Evernote says this is an IFTTT issue. I'm a paying premium member of IFTTT, so maybe (hopefully) I can get a response from IFTTT support on why their automation turns on the public URL, but doesn't bother to turn it off when the automation completes successfully. Turning my notes into public notes without any action on my part (or up until this point, my knowledge), is not cool. I'll report back if I can get someone to respond on this.
