I find much the same mindset among many Windows users who try to switch themselves over to Linux. They come in expecting Linux (a Unix alike) to be exactly like a "free Windows", which it simply is not and never was but that's what they think it is for some reason. I always make it a point to explain up front that Linux is an entirely different operating system, and while there will be similarities that will be immediately obvious, Linux is not a Windows-alike, and there will be learning and adapting involved. Folks who go into such changes knowing what to expect tend to cope far better with the differences than those expecting something to be an identical clone of what they're already familiar with. I assume the same likely holds true here as well. Those who go in expecting exactly Twitter, but free and distributed / decentralized are going to be sorely disappointed, but those going into it knowing to expect differences won't be caught by surprise the first time they are confronted with something that doesn't operate exactly as they thought it would.
