If something's "free" either someone else is paying for it, no one really values it, or there's way too much of it. Free also means people providing it may be doing so at a loss. Aim for cheap enough that you can afford it but profitable enough that people will provide it.
Liberdon is a Mastodon instance for libertarians, ancaps, anarchists, voluntaryists, agorists, etc to sound off without fear of reprisal from jack or zuck. It was created in the wake of the Great Twitter Cullings of 2018, when a number of prominent libertarian accounts were suspended or banned.
