not necessarily, it can be a benefit to use a second anonymity network for “less secure” tasks, that’s why we disable Outproxies, we don’t need to use an inferior Network for clearnet browsing, we use Tor for that since it performs better than I2P atm.
the current goal is not to create a I2P Whonix Version, we want to have both Tor and I2P first. a I2P only Whonix version would come probably after that, but i see more benefits in the first Version.
Tor has clear advantages in a few areas.
why would you not use them ?
Yes Tor has also disadvantages, but there is no reason in disabling it by default, we can have I2P as fallback for the Services we use with Tor. China is blocking I2P, there are People on the I2PForum confirming this.
only if Tor is blocked, or once we got an I2P only Version.
feel free to help with that, as i stated above i’m currently in no position to test much. so it will take a few days…
