this is not a personal matter. It's a public issue. For example, there are plenty of Arab businesses that boycott Israel and their products. Are they mixing work and personal issue?
It's not a public issue. He didn't support the anti-gay marriage bill as a representative of Mozilla. He did it in his free time and as a SINGLE person. I absolutely DO NOT agree with him, but that has nothing to do with Mozilla or his professional work. I don't support either boycotting any Israel company, but if that company supports Israel apartheid by any means, then yes, I do support its boycotting. And if Eich does anything anti-gay as Mozilla CEO (e.g. ban gay employees), then I would boycott Mozilla as well for letting CEO's personal beliefs interfere with the organization proper working and he should be dismissed because of unprofessionalism as well.
It's not as clear-cut as you suggest. You can't just draw lines between his role as CEO of a company and his public stance on an issue and call them separate. It does affect the company and the impression that other employees get. It affects the company culture. It on one hand makes homosexual employees feel that the CEO despises their lifestyle so much, that he's publicly willing to donate to not allow them to lead it. On the other hand, it enables the bullies to take this as a green light since their values (based on hate) reflect that of the CEO.
