Looks like it was mined from somewhere and combined with other data...
Unless people are putting their github urls in the contact apps?

That entire market needs to be killed off with hefty fines.
This stuff happens, at a low level, and prosecuting it is expensive and makes little real difference so why bother?
It's not even like busting shop lifters and petty burglars where at least you make the victim feel better by arresting somebody even if it likely isn't cost effective overall.
They wrote up all of their information and sent it to the police who came back with: "Yeah, thanks. Here's the thing: this is non-violent crime and the total amount stolen is less than GBP 100,000" (don't remember the exact number but something thereabouts).
People like to think that the police are salivating for every crime that could come through the door. More realistically, they are an overworked group with less resources than they need to tackle and or solve many of the cases they are presented with.
Plus, just like you, they have to prioritize their work based on various dimensions of incentives such as what looks good to their boss, what is hard vs easy etc. For example, do you tackle the case that is small and easy to close with not a lot of publicity or the big case that may be harder to close but will net big wins in the PR budget?
Easier to prove too.
Not sure I'd go so far as to accuse a specific company on a public forum. But in this regard, the idea that a contact management app could be behind this DB is plausible.
