I don't agree. The simple fact that Lemmy is decentralised is a political thing. It's about who has power over the platform, and that is inherently a political issue. The status-quo of other platforms, that being under the control of a corporation, is also a political stance.

PS: everything is politics, that's not a good or bad thing, it's neutral. If you don't think of something as political, that just means it's oriented towards the status-quo you are used to.
