You're saying that "[you] hate the way the cryptocurrency world has sucked all the air out of the decentralized room" but also that "we already have tons [of decentralized apps] that do not [use cryptocurrency]." That seems contradictory.
It's not contradictory. When they say they hate that cryptocurrency has sucked all the air out of the room, they're saying that they hate that nobody is talking about the non-cryptocurrency alternatives, not that they don't exist.
