this was written by someone who hasn't used I2P much, because they seem to be completely unaware of outproxies.
Edit: After mentioning multiple times that it was not possible to browse the cleanet from I2P, they say:
Although it’s technically possible to use an I2P connection to browse the regular internet, there are very few exit nodes, and the ones that exist are often quickly taken down.
I've been using the same outproxy for six months in a row.
Edit 2: okay, I've finished reading the article and it's pushing NordVPN. They've lost the little credibility they had.
