There are already so much confusion from people about Bitcoin... If you now tell them, that they are making it even more complex, by splitting it into 2 versions... you will be doing more harm than good.
I had a uphill battle trying to explain Bitcoin to NEW people... I can just imagine what they will be thinking now...
We have to make some hard choices NOW.... and this would not have been neccesarry, IF these developers had put their self interest and agenda's aside, and made the success of Bitcoin their main goal.
This will either make or break Bitcoin... We will soon see.
