Devs warned that there will be consequences , the GPU miners decided to ignore them . As i said being dishonest doesn't pay as much as being honest . Miners could give the code and keep their stash and keep earning . They became greedy and lost everything . In fact , they are so dumb that didn't even ask the community to provide them a percentage of each miner rewards that could use their code , i think that no one would disagree at that time ( take a look at how other cpu and gpu miners had a dev fee ) . They chose a way that left them with their d**ks in hand , i guess that's better for them than to act logically by using their brains . That's what usually happens when you think with the wrong head .

As you said miners act at their own interest . So do devs , but not for their personal interest , for the longevity of the project . Not all people act like you did . They are not getting paid and they commit their time to create something useful . I've seen for years scums that provide nothing to a project and just want to earn everything . Devs here want to provide to others , you are just looking to steal from others .  

As for the part that users don't trust noso , take a look at how many people are mining right now , there's been an increase of at least 5X. Noso is steadily increasing it's base , not everyone believes in the far west world you want to live in . Participants know that if they act honest they have no problem . It's a project that tries to have one of the fairest distributions , and so far i think they have achieved it . So , you can follow their way or hit the highway .  

Edit . Kαι o μακαριτης εδω ?
