This principles page doesn't seem to have any irrelevant politics to me.
Permacomputing seems like a body of values and practices that is extremely grounded in a particular political perspective.
It's odd to regard permaculture, degrowth, anarchism, decoloniality, intersectional feminism, etc. as completely orthogonal. They're all part of a shared tradition of thought—not an "omnicause," but an ecosystem. You won't find a lot of people who love intersectional feminism but hate decoloniality. Appropriately enough, plucking a single plant from the earth and then dismissing the rest of the garden is exactly the type of blinkered thinking which permaculture discourages.
In any case, I detect an omnicause because people are sloganeering on its behalf below:
"If you see this as political, you should fix yourself", "computing is related to colonialism", "everything is political" etc.
