Except 3d printing has a much bigger open source community than 2d printers have.

There's already software out there that can optimize the output file of a slicer - effectively rewriting the gcode. Removing any watermarks at the code level seems pretty trivial, even if every single slicer company relented and added this function

Presumably this would be handled by the printer firmware and just slightly change the extrusion rate, regardless of the gcode.

Easily solved by using open-source firmware.

That's true, and that also goes for printers. However most people will use it out-of-the-box. The people who want to avoid tracking, yeah, this won't do shit.
