Well.. Tor can create trouble for you as well, or at least it did for me. I used to sometimes go through Tor to visit competitors' websites when I used my work computer, just because I didn't want to leave a trail of my company's domain in the competitor's logs. That was quite innocent I thought. Then my sysadmin informed me that the national security monitor (or whatever it was called), which my company was connected to, got an alarm on that. Turns out they had a trigger on Tor connections because they considered it as something used for malicious purposes. It's even triggered if a passive Tor application is running on a mobile device connected to the wifi guest network, b/c it may sometimes probe a node even if not in use. So, uninstall it is. If it's that easy to monitor that someone is using Tor I don't see how it can actually be used by anyone anywhere, where it matters (for something more important than what I used it for).

I was under the impression that law enforcement has established a large number of Tor exit nodes, allowing them to unravel the onion (so to speak).

That’s not quite true.

Freenet protects communication — content in flow. Somewhat larger files that are not accessed automatically disappear from Freenet after a short while.

Tor protects your connection to another computer.

The stated usecases are excellent examples for usage of Freenet: information for transgender people or about abortions. Even accessing such information can get you in danger nowadays.

And a site accessed via Tor can more easily be compromised (to get your identity by tracking information from your OS or similar) or taken down (so the information is gone).

Plenty of pertinent information exists as documents, like lists of abortion providers or how/where to get hormone replacement therapy, etc. Freenet can be used for such content and would save a person from having related search queries and sites in their normal web history/traffic that can later be used against them.
