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?
I would also say that this is because anonimity is not needed by all countries. I know that in Spain torrenting is not a big issue and ISPs don’t care that much (even though distributed Copyrighted content is still not allowed). They usually go after people profiting from distributing copyrighted company rather than people downloading or distributing for free.
Disclaimer: I think some of my info is a bit outdated so if anyone has more recent info about Spain’s situation please tell me.
I’m from there and I can confirm this is still the case nowadays.
