Soon they will use the open source software to develop their own blockchains, without ever expressing gratitude to satoshi or the bitcoin community. Isn't that stealing?
I do hope that whoever resorts to blockchain gives enough and sufficient credit to Satoshi Nakamoto as a sign of respect and gratitude.
Yet, as blockchain was declared an open source software, Satoshi Nakamoto for sure knew that he is allowing any person to modify, enhance and use the source code as they deem needed. So with due credits or not, the blockchain was decided by Satoshi to be open and free for all. I guess he was not expecting anything in return but for the technology to be used.
