Using a weapon can be done for good. If they’re using it to attack something for their interest, it’s weaponization. However, they didn’t do it for “good.” They did it for self-interest. US representatives got bombarded with phone calls and messages telling them not to block a foreign company’s app after the company told them to do so. What would that look like to them? It looks like a weapon that has been turned on them.
We shouldn’t just accept foreign agents interfering with our election just because “who doesn’t these days.” That is totally the wrong response. If that’s all you see in this you need to re-evaluate your position.
