Bitcoin Unlimited probably could have been named a little better, to avoid confusion from the implication inherent in the name. No matter what naming convention, language etc., though, there will always be some confusion about what is actually meant.
It's fairly straightforward and easy to understand as long as you remember to read passed the headline. The "unlimited" part references the transactions, not the number of bitcoin.
One of the big problem that I am seeing about bitcoin, is the people itself, because they are just after the money that they will benefit from it, they don't realize one of the reason why bitcoin exist and that is to be able to help and make change in the economic system and make the society cashless.
