That page is literally 1 click from the main irs.gov site. Granted, it's "below the fold", most people will have to scroll down just a little bit. But there it is: IRS Free File.
Go ahead, naysayers, downvote me all you want, but I'll say this: if you can't find that page and investigate if it applies to you, then you deserve to pay to file.
It's a totally different discussion if the links from the IRS site lead to dark patterns and tricks. That's a legitimate topic of discussion.
But not the existence of IRS Free File itself. That's just fine. About the only way it could be easier to find that page would be if it were "above the fold".
