As the author admits, there's lots of good interests in keeping Tor a thing, and nothing good can come out from removing it.
Such people sharing illicit material should be investigated and prosecuted (with severe and appropriate court orders) through the ordinary means, but the author doesn't seem to have a good solution on hand, other than showing provocative questions like "why are we funding these Tor guys".
There's no single solution that they can implement TOR-side without breaking the whole point of the project. They won't implement any backdoor or similar bullshit, no matter what. There's no point in TOR if they do that. May as well disband the project.
