So, I see this as rationalization.
The fact is, you took a leadership position, and later turned your coat for reasons that perhaps made sense to you. But they don't really make sense to anyone else. So, yes, everyone who supported you then is going to feel burned.
You also made yourself a paid voice that was often hostile to Free Software, all the way back to the SCO issue. Anyone could have told you that was bound to be a losing side and you would be forever tarred with their brush.
So nobody is going to believe you had any reason but cash, whatever rationalization you cook up after the fact. So, the bottom line is that you joined a list of people who we're never going to be able to trust or put the slightest amount of credibility in.
And ultimately it was for nothing. I've consistently tried to take the high road and it's led to a pretty good income, I would hazard a guess better than yours, not just being able to feel good about myself.
