Lemmy is always going to lean more radical than other platforms. Not only is the lead dev a Communist, but to pick Lemmy over Reddit is an ideological choice to begin with. There is an ideological barrier to entry, and this won't change until Reddit goes under.
For me picking lemmy over reddit is a matter of liking the software a lot better. As a dev myself I think lemmy is much more elegant and usable, and IDGAF about the lead dev's ideologies, as a dev they kick ass.
