That is horrible IMHO. This license is completelly not free software.
In hand you are getting the profit from free software like BitCoin (the whole idea), CryptoNote, ByteCoin and Monero. Without them you would have need much more time (maybe 100 years!) to get to the point where you are now in the development.
But in the other hand you are breaking with the free software chain and releasing your new code as non free, so it can only be used for research (WTF?).
That means something, dero team, you are doing this just for your own profit, not for the innovation or advance of blockchain related technologies. That's not the crypto thinking way I'd support.
Still I don't understand what are you afraid of? What's the thing? Someone will make a fork and release a new coin, so what? You are the trusted developers and you will have always the first position on this field, unless you loose it by doing stupid things. Look at Bitcoin, Ethereum, Monero, IOTA and so on.
Finally I would honestly suggest you to rethink about this matter. Release the DeroSuit as free software (GPLv3 or AGPLv3), then your 2 Milion premined coins wiill worth something one day.
I'm going to have to agree with p4u here. As someone working in a datacenter security startup it is vital to understand that having first mover advantage while helping move the space forward for a specific subset it vital for company legitimacy and trust. It doesn't matter if the code is shared and someone re-purposes it, since the Dero team will always be able to iterate faster than the the person using the codebase since the dero team wrote it.
