Well, that's just not the case. Lemmy's devs have always been highly ideological. The case in point here is their handling of the slur filter.
The basic guiding principle of GPL software has always been freedom. Free software has always been explicitly political, but when you put out free code, you have to accept that it might be used by people you don't like. Adding DRM, such as the slur filter, is against the freedom and openness of the free software, even if the DRM is so half-assed as a slur filter that any half-competent dev could easily remove.
