The point is that it's hard to digest a subscription scheme without some of these features as part of the deal. Sure, we can use github for collaboration. Sure we can use dropbox for cloud service. Sure we can use third party addons for functionality etc... if that's the case, fine, I have no problem with that, it is exactly what we've been doing with C2 already. But some people are going to be upset about having to pay a subscription to do those things, so don't be surprised about that.
