I think it's fair to say that the software itself could/does facilitate illegal uses cases. But with that line of argumentation, then all software facilitates illegal use-cases just by existing.
The statement "We do not endorse, promote, or facilitate copyright infringement, illegal streaming, or piracy in any form", might be poorly written with regards to the fact that just by existing this torrent streaming program _does_ facilitate piracy, but I don't think this was your original argument.
