I kinda got bored halfway through. From what I gather they're salty that GitHub is switching to react? If that's the issue then the headline is rather misleading isn't it?
Surely legacy software is one that drifts into obscurity through lack of investment which is the polar opposite of GitHub rewriting their entire front end..
Why not just give it away for free? It always seems odd to me that games just disappear rather than being allowed an elegant death of old age.
