Does Intuit violate personal privacy

The company claimed that a purchase of TurboTax could be used for 5 federal files.  However, Millions American encounter a problem as they use the software. Commonly people will received this message "This license code has already been associated with an account. Please check that account and look for it in Downloads" I spoke with the Intuit customer service. They said to share or use the application to its maximum benefits, all the five fillers must registered within the company website with A single e-mail address and shared a COMMON passwords (equal access). That is saying the 5 entities MIGHT see each other's return ( in dollar amount) at post-filing stage. Is it ugly? or does Intuit violates federal privacy laws by practicing such eel?  I would not say the INTUIT is very reluctant letting filers using their software to the top utilities, but technically, we were cheated by the company for years.
