Release the code, yes, actively help FC, no.
What about other copycats?
Basically the same as for Nxt: if they can't survive on their own, they don't deserve to.
If they can't survive and THRIVE on their own, they don't deserve to.
Let FC take it from what ever he has now and let's see how much of an upgrade he can make.
I have said before and now I am going to say it again if NXT want to survive in the long-term, we need to focus on decentralization and community involvement. Superior tech won't cut it in an open source culture. Only an ingrained culture of decentralization and community involvement can create a rich eco-system and set NXT apart. That's also what set Bitcoin apart from all other clones, not superior tech.
Now be a NXT-er and go here to vote https://bitcointalk.org/index.php?topic=423241.0 . That's what we are making; creating a culture of decentralization and community involvement.
