its the matter of them calling these other networks bitcoin2.0.
I think you'll find, in the example
you linked to the ONLY person to refer to it as "
bitcoin 2.0" was
YOU.
I was thinking the same thing: I've only seen "Bitcoin 2.0" used by franky1. But in the topic you referred to, 9 posts above franky1's posts in which he mentions "bitcoin2.0" 5 times, it's mentioned in some shitcoin's signature:

all these subliminal and subtle hints that it IS bitcoin2.0.
Maybe the "subliminal" signature worked on franky1?
I honestly can't communicate with franky. It becomes impossible for me after a while, I don't know about others.
I feel you:
I'm not a native English speaker, and it's kinda hard to understand what you mean if you talk about "altnetters", "flip flop", "waffy clauses" and "flip floppers".
