I agree about the general idea of not throwing stones into the sky. They have a tendency to fall back down on one's nose.
However banning tools that were 'snuck in through the back door' because of their efficiency and because nobody had the heart to follow the actual procedure to get them through the front door strikes me as profoundly childish. Especially if it is done as some sort of vengeance, or 'just because we can'. In fact about just as childish as throwing stones into the sky.
I'm being a bit idealistic here. There will always be turf wars in BigCos. But hey if some people switched from trying to look like the best and brightest to getting stuff done instead, i'd be all for it.
