I don't have the answer but freenet isn't it.
There are legitimate reasons to use tor, but onion sites don’t seem to be part of it, and when I’m evading censorship to watch Netflix or something I’d rather use a vpn.
Freenet is more like a depository of documents, so you can't really host a site on it, there is no 2-way communication. In many ways it's a predecessor to ipfs.
In a liberal democracy, it makes sense that its use cases are mostly criminal, because the censorships it evades are mostly eroded by social reform. Those who are left are not hiding from censorship but from democracy.
However, when democracy and liberty are set aside, by fascism or war, these tools really shine. (E.g. BBSes being run on network printers during the wars in Europe in the 90's.)
