I found I2P much better than Tor network, and now it supports BitTorrent protocol too https://geti2p.net/en/docs/applications/bittorrent .
Why haven’t the pirates migrated to I2P? Why are we still using clearnet and making people backout of seeding cause of DMCA?
This is the best answer. The software just has to mature a little bit more. But it’s a matter of time.
Once we reach the phase where most mainstream bittorrent clients support I2P by default, it will become the new standard.
Most people don’t use bleeding edge features.
