When did OP blame the people involved personally?

If I to hire a contractor to redo my roof, and that roof leaks, whether they worked hard or not is immaterial. They did not do the task in they were paid to do. I'm not going to buy their services again just because their shingles guy was particularly charming.

MS has talented engineers, but that's a complete misdirection. Github is a service in decline: there is nothing wrong with criticizing them.
