This is a part of a larger issue, obviously, but this specific part of the problem could easily be resolved with tax reform. The IRS knows exactly how much you owe them so why do you have to pay a 3rd party to prepare it for you? Apparently in other countries the government tells you how much you owe and you just let them know if you disagree with that amount for some reason.
But that type of tax reform won't happen because these companies dump massive amounts of $$$ into lobbying.
We're done with the platform but there are a lot of real people still using it. I do think the quality is going to tank and they'll continue bleeding users though.
