This is why many of his core supporters sold their SPR and joined the Crown community and team over a year ago in order to develop their ideas.  Notable that its only those SPR team members who still have their SPR that are creating HLM and the coin swap.

Those that sold their SPR and bought CRW instead have over x100 their money and have  year of progress under their belts.  Maybe the HLM team will be able to do the same for their huge SPR bags and also deliver a good/better product in time.

EDIT:  I don't see anything unethical going on here, but I think its important to recognise the motivators behind these moves.  One group of SPR devs decided to join another project and implement their ideas without a PR and marketing funfair, and the others decided on a coin swap and sales drive on a product that isn't built yet.  Will be interesting to see how each project does over time.  There is no right or wrong approach. Just the approach that feels better to you ethically.  I do think that it is telling that Bittrex have a good relationship with the Crown team but HLM is partnering up with a low volume exchange for the swap though.
