Taken away by whom and on what basis? I would dispute that you need the ability to take away other individuals' ability to lawfully write software. That ability is bound to be abused for political reasons (which is also what it looks like when people have reasonably different ethical systems and one imposes his by force).
Anyway, the issue at hand is bad corporate behavior, not bad programmers. I don't see why we need to start licking our chops about the prospect of forming a blacklist against individual programmers.
This is just a bonding/licensing arrangement, it's in use by every other profession that has this exact problem.
So go ahead and try and stop bad corporate behaviour, everyone else can use a proven system so that programmers can easily say "no" when asked to do something unethical and not be fired for it.
I'm often confused by how often programmers completely reinvent the wheel when faced with social problems. The idea of looking to other similar industries never comes up, even if the problem is exactly the same.
