I find hypothetical scenarios quite challenging.
I suppose it's possible the people within mozilla may pull another "mozilla" and spawn a new company made out of many of the same people to maintain its codebase.
I think it's more likely Mozilla, as an organisation, would fire or enfeeble Brendan Eich before that happens.
I only recently learned about the donation, so you have no idea the cognitive dissonance I have been going through.
I believe that, as a champion and a leader, you can't get anyone better than Brendan Eich for the free software movement. But as a symbol, and a figurehead, the donation is really problematic. If it had never come to light, if he had never revealed his inner feelings about homosexuals, would it be a problem for mozilla with him in this role? Maybe, I doubt it though. I think he is utterly professional at keeping those things seperate and interior.
On the other hand, it could very much affect his leadership abilities if he ever has to work directly with someone he knows to be gay. Or many someones. Or an entire company of someones.
This is not to justify his donation. Which was a bad bad idea on his part, and bad ethically speaking too, not just because he got caught. but that I think it's not enough to discard a whole person over.
But on the other hand..
can you sense my cognitive dissonance?
