At a former company (which has since gone out of business) I met some people who loved Evernote.
One was an administrator who cheerfully kept confidential details about the security of our corporate network in it without once reading the Evernote TOS or considering the consequences if those TOS changed.
Even after I explained that those TOS clearly violated several parts of his employment agreements, he continued to use it. He didn't think there was anything wrong since our CFO also kept a lot of sensitive information in it...
