That is better than nothing, but having only such a short part of the whole thing makes it hard to reason about with the bigger picture in mind. If there was the usual diff header, it would be a bit easier. Considering that it is also outdated already, I do not feel like investing time into figuring how it works. I hope you understand.
Your point is fair,but keep in mind that there were people with legitimate claims like yours back then, asking for open source. The fact that this is delivered now, proves the team's dedication to open source and justifies their course of action. I strongly believe there will be shitcoins with this tech from now on
