sharing turbo tax with my immediate family

For many years I would purchase turbo tax for my 4 children and help them with their taxes.  After they got married they did their own and we could share one CD disk for the 5 of us.  Now it looks like that Intuit no longer allows that unless of course all 5 of us can have access to each others tax information which is unfathomable that they would dream up such a stupid idea.  Why is it that software companies become successful and then somehow lose their way and shoot themselves in the foot?  I have had issues with TurboTax in the past and thought about trying H&R block but haven't pulled the trigger.  Intuit just gave me the motivation to do so.  Apparently I can transfer all my info from Turbo to H&R.  I understand that the IRS plans on providing their own free software at some point.
