I don't know, thinking more about it, I frankly don't understand both why on earth you would feel responsible for this, and why do you think that this would ultimately be a lesser harm. It really sounds to me like you are not putting anyone at risk and ALSO that this change of license wouldn't actually help anyone.

I even understand the argument that copyleft might be detrimental to some projects because of big for-profits contributions, but this reads like a cop-out "for free". I would understand a change of license to protect your own ass (without advocating for others to do the same), but this is saying "I don't do copyleft because someone, somewhere, might be hurt by an abusive corporation or state for reasons vaguely related to my choice of license".

By this logic, knowing that your project benefits the interests of those who jailed innocent workers, shouldn't you just take your project offline altogether? Aren't you worried that you're actually taking agency away from both those workers AND from people trying to offer an alternative to those clearly evil corporations?

I'm sorry it's not even your decision that's driving me a bit nuts, it's your work and you license it however the fuck you want, it's the logic behind it.
