I think that would be fair to say. I mostly run it to contribute to the network, so that other people can communicate or share files more privately. (On OpenSuSE, it can be installed from the repo and just run with no special configuration.)

In some ways I2p is more secure, but it has its own pros and cons. It’s primarily used with services & sites within its own network, similar to onion sites, and used that way it’s said to be faster than Tor. It can be used for torrenting with a client that supports it, like qBittorrent or BiglyBT, without harming the network. There are outproxies you can use if you want to anonymize access to normal websites, but there’s only a few of them, and it’s slow. You can have it and Tor running at the same time without them interfering with each other, though.

It’s more similar to tor than a vpn.
