As someone in the US, there have been numerous free options for filing your taxes for a long time (even officially endorsed ones), and for most people without complex tax situations, it is indeed quite simple and only takes a few minutes. The people who complain about taxes in the US either have uncommon situations, didn't understand the tax implications of an employment arrangement prior to tax season (e.g. became an independent contractor without realizing their responsibilities), or are simply unaware of the free and easy options that have existed for a long time.
