I think that it's manifestly unreasonable to preemptively knock out communications in a large civilian area during peacetime for essentially any reasons; in that same vein, it's absurd to lay blame at the feet of a communications enabler who provides a means for individuals to escape authoritarian suppression of communications.

The only parties responsible for the violence you are implying would be the individuals actualizing the violence, the individuals originating falsities, and the governments who fail to actively maintain peace. The collective failures of all three to restrain their actions amidst uncertain rumors should not condemn the vast majority of peaceable humans from communicating with each other.
