Which is really the main issue. Offering a more accessible free version to file taxes is great, but the real problem is the need to file taxes at all for a lot of people. The IRS already knows the relevant info: Your employer sends W-2 information, your bank and broker are sending the various 1099 forms for interest, dividends, stock sale gains/losses, etc. Same for your spouse and kids/dependents. Don't even need to itemize in a lot of cases, since the standard deduction is preferable in many years.
Unless you're dealing with foreign income, are a business, or do a lot of contract work for cash, I don't see much reason why the IRS can't just handle all the taxes automatically - apart from the fact that some company wants to charge me $150 a year to file my taxes and making sure that my tax situation (which would fit on a beer coaster otherwise) is as complicated as possible.
