This reminds me of something that I thought of late one night that I feel needs to happen: tor, or something like it, distributed as the payload of a virus. Hopefully a very serious one.

Then, even if things get patched, it's mere existence and prevelence among the layman gives you a tremendous amount of plausible deniability while also increasing the strength of the network.

However, it's quite morally wrong to do so. I guess it's just one of those late-night thoughts.
