    I’m curious, have you tried SumatraPDF (uses muPDF under the hood)?

    Do you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ if it also has the same issue? Thank you!

    There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)

    FWIW, https://github.com/sumatrapdfreader/sumatrapdf/issues/1249 ("Support form filling for at least 1040 irs form") has a comment saying "MuPDF-GL has the capability to edit fields and save the PDF" of a 1040.

    I have just learned the Firefox 93 added support XFA - https://techdows.com/2021/10/open-xfa-pdfs-in-firefox.html .

    So it would appear there are free software solutions to XFA forms.

    Just because something doesn't seem far-fetched to you, doesn't mean most people will regard it as far-fetched.

    Many people all sorts of "sectarian objections" - far more than there are SovCits or other tax protesters. Stallman has never come across as a tax protester. Ergo, I think it's far-fetched that "sectarian objections" is strongly associated with tax protests.

    Further, at https://stallman.org/archives/2017-may-aug.html we can read Stallman opinine that we need to "return to the "bad old days", when Americans in general could have a decent life, not penury; when the US could afford to build what the public needed instead of privatizing everything with a toll" by making taxation more progressive. At https://stallman.org/archives/2011-jan-apr.html we read he supports "The Fairness in Taxation Act [which] would raise taxes to 45% on incomes over a million dollars a year."

    If you are going to run something in wine, try sumatrapdf. It's FOSS but Windows only. (sadly, but runs great on wine)
