They are both shit. Siacoin devs want to hardfork to add some billions of coins into their own wallets.
That info is wrong.
This was a post from a dev who was thinking out loud of how the team
could raise funds. This was never an official statement nor a team expression.
The Sia Devs are very open in communication, in this case maybe a bit too less sensitive.
Three days ago they got a grant and announced in Slack:
Nebulous has received a generous grant from INBlockchain, to be used for the development of Sia. Li Xiaolai quotes: "don't worry about money, just have things well done".As a part of this grant, we are committing to not forking the blockchain to fund development, now or in the future."
