The Free Software community has always been political. Where have you been?

Introducing a non-binary mascot for KDE is no more or less political than for example Richard Stallman demanding that printer drivers should be free, back in the 1980s. And same way the use and preference of the term "open source" over "free software" -- or vice versa -- is also very political because it depends on if one wants to go with the described values or not necessarily want to stand behind them.

The Free software community involves people, and with people come shared values and politics. That's kinda what "community" implies. And if we really want to go into it, given the circumstances of the invention of things like computers, the Internet, etc. it'd be very erroneous to asset that software in general has ever been value-free or non-political. Computing artillery trajectories is political just the same way as promotion of LGBTQ+ people, even if people get more upset about the latter rather than the more kinetic kinds of politics implied by howitzers et al.
