They have some private repositories (as far as I know for Core V2 and ArkVM). An advantage is that they are less exposed to plagiarisms (Ark commander, Lisk commander, are you kidding me? Arcblock's chain adapters = Ark's encoded listeners). Open source = everyone can take some lines of code and make their own version, but come on, those two examples are just copy/pasted
Yes, I see the copycats out of Ark from these scammers is some real issue because they don't give Ark credit. You know even the Lisk website is exactly the same as Ark, layout and content, they just changed a little bit and from Ark to Lisk.
I have no doubt Lisk and others projects are waiting for Ark to release something so they can copy and claim their own, especially the Bridgechains/sidechains thing.
The EOS world hackathons was done by the Ark team years already, they're still claim to be the first one.
I even start seeing this Tron scam shit trying to use the red filled rectangle Ark team been using plus a few other scams also try using the rectangular filled color, it sure do look more standout and legit to them. Oh, Tron website and info is look like fucking little kid joking around of taking over the world. It's seem to me Ark is the real king everyone just dying to copy from, or perhaps I pay too much attention to Ark. It seem something Ark team put out then expecting these scammers are copying like wildfire!
It means higher profit multiplier when we go back up!
