I did not have that experience. I went directly to the site and my federal was free. State was $15 or whatever it was. I did not use the IRS link.
This IRS link issue is something I've noticed with TurboTax and TaxSlayer in the past. They hide their free file (even the Federal File) from users unless they use the IRS link.
Or, unless you're saying I should believe the marketing, but again, we're in a thread about the marketing from companies in that industry being false…
