My issue is that so many people think that means I2P (thus Monero) is safe against the NSA (and the 5 Eyes countries and the German Stasi which is still active btw), which is what I mean by marketing (whether untended or not). I wanted to make clear I2P can't be relied on for that threat model.
I'm pretty sure that every significant discussion of I2P and Monero has stated that won't make it NSA proof.
I'm also pretty sure that merely improving a mixnet won't make something NSA proof either. The threat model is much wider than that.
