This basically invalidates the entire premise that it was an innocent mistake. It's impossible for me to believe that you actually thought that people wouldn't care about 100% of their commits being attributed to Copilot even when it was never used. Either you're misconstruing what you caught with the testing beforehand or your entire development process is tainted, because there's no way that a non-evil corporation would see this default behavior and think that people would be fine with it. It seems far more likely you just thought you could get away with it.
I think many people agree here.
