Super shady. They trick people who are eligible to file for free into paying fees. Then they pay lawyers to help them avoid refunding those fees to low- and middle-income people who never should have been charged fees in the first place. They gas-light you with commercials that make you seem stupid for questioning whether the service is really free. Then they trick you into using what appears to be their free-file service. Then after you do the work to prepare your taxes, they charge you fees!
