Sentinel dVPN does/did the same thing. You'd connect to their network, pay a Node operator directly with the network's coin, and you'd use their connection. Don't know how safe it was, with respect to seeing the through-traffic, but it did work.
Lemmy.one is run by the guy who runs privacy guides.org. That being said, if you look at the small list of communities he created, I guarantee that he won't allow any conservative views there either. There's one privacy community and 4 or 5 alternative lifestyle communities.
Better off making your own instance at this point. Most of Lemmy is liberal/left wing regardless of what their sidebars say.
