Status.im hasn't done much other than raised a huge round of ICO, so they're sitting on all this money they can use to buy out other "competitor" protocols. Sure, they have a prototype beta and I guess beta testers are using it, but they don't even have a working app on the appstore.
Their (Status.im) strategy seems to be use their treasure chest of money and gain traction by acquiring other protocols (It may sound like a "partnership" but essentially the whole deal seems to be that these projects that received investment are expected to integrate with Status token)
I would have no issue with this approach if they actually HAD launched a product, but like I said, they don't even have a production app.
Riot has been around for a while, and they have an actual product. I think it sucks that an organization with more money can just buy out another org with less money. I would have loved to see Riot build their own destiny with their own tokens instead of raising capital from a competing messaging protocol.
