I think it's an interesting and noble social experiment.
Maybe it doesn't amount to anything, but that's easy for the pessimist to say. What if it does?
So what if the average person doesn't do anything directly, awareness in itself is power. Politicians and people in power do not care about issues that their constituents don't care about. If this builds awareness then it becomes a bigger issue as a whole, and I don't see how that in any way does anything but help.
If there was more vocal public outrage and knowledge about what was happening in the German death camps in WW2, perhaps the allies would've made it a higher priority to bomb the rail lines to those camps that took so many people to their deaths. Today we have a tool that wasn't existant back then and that's the internet, which connects to us to things happening everywhere around the world in real-time. This is a big difference.
And really so what if you spared 30 minutes to watch that video. You likely would've been jerking off or watching some stupid Youtube videos or Facebook time-wasting ... at least now you're at the very least aware of something else that's happening somewhere else.
