Only insofar as political neutrality is interpreted by the modern polarized political factions as a political stance.

The GPL "tolerates" conflicting political opinions, which used to be closer to the norm and thus not political.

The GPL mandates that if you modify and distribute GPL licensed software, your derivative work must also be free and open-source. This ensures code cannot be made proprietary.

Other than that, there is no expectation of political stance.

Only in the current ultra-modern age, has politically neutral devolved to meaning that you must agree with me on 99.99%.
