No serious person could believe that you lose your 4th Amendment rights because someone does your taxes. The USSC ruled incorrectly.
Information you give to a business, becomes that businesses records. Which are subject to normal government oversight by subpoena.
You give up your privacy when you share them with others.
It's funny that when the government does the same thing to a democratic politician or to some slimy business person the republicans have no problem.
trump even did it. He had the DOJ subpoena the records of journalists and even the White House Lawyer from businesses like Apple and Microsoft. Those companies handed the info over and the judge put a gag order on the companies so they couldn't even tell their clients they were forced to hand over the info.
I started a thread about it.
The replies from the trump people was they had no problem with it since there was a subpoena.
Yet they have a problem with it when it's trump's records.
