Satoshi Nakamoto create open source Bitcoin for that reason. To everyone copy and create another version of that Blockchain system.
This is the idea I like behind BTC. The fact that it was written and left open for future programmers and people to take apart, modify and learn from.
This is a great part of bitcoin the open source is an example of giving to the world and that is always good
When i first heard about this i thought it was bad for business but they are going to give bitcoin free publicity whatever they do with blockchain technology so i am less worried now but i do wonder why they did not just use bitcoin and not start another shitcoin. BTC will remain number one that is all that matters here..
