Intuit's invasion of the privacy of desktop users is akin to the conduct of Facebook that resulted in involvement of the Federal Trade Commission.  Perhaps if enough of us filed a complaint with the FTC, something might be done.  Complaints can be filed here:  https://reportfraud.ftc.gov/#/assistant.  That Intuit purports that the sign in requirement is for our own protection when, in fact, it creates more security risk can, arguably, be considered a form of fraud.  Some may also have the option of sounding off with their respective state Attorney General offices.
