One of the appeals of open standards is that they allow market forces to work. Consumers can choose the tool or service that best meets their specific needs and if someone is a bad actor, the consumer can flee. Centralized proprietary services, in contrast, tie you to a specific provider. Consumers have no choice if they want/need to use the service.
It’s not as great as it sounds
This is true in theory, but reality is more complicated. Centralization allows for lower friction. Counterintuitively, centralization can allow for greater advancement. As Moxie Marlinspike wrote in a Whisper Labs blog post, open standards got the Internet “to the late 90s.” Decentralization is (in part) why email isn’t end-to-end encrypted by default. Centralization is (again, in part) why Slack has largely supplanted IRC and XMPP.
Particularly for services with a directory component (social networks for sure, but also tools like GitHub), centralization makes a lot of sense. It lowers the friction of finding those you care about. It also makes moderation easier.
Of course, those benefits can also be disadvantages. Easier moderation also means easier censorship. But not everyone is capable of or willing to run their own infrastructure. Or to find the “right” service among twenty nearly-identical offerings. The free market requires an informed consumer, and most consumers lack the knowledge necessary to make an informed choice.
Decentralization in open source
Centralized services versus federated (or isolated) services is a common discussion topic in open source. Jason Baker recently wrote a comment on a blog post that read in part:
I use Slack and GitHub and Google * and many other services because they’re simply easier – both for me, and for (most) of the people I’m collaborating with. The cost of being easier for most people I collaborate with is that I’m also probably excluding someone. Is that okay? I’m not sure. I go back and forth on that question a lot. In general, though, I try to be flexible to accommodate the people I’m actually working with, as opposed to solving the hypothetical/academic/moral question.
Centralization to some degree is inevitable. Whether build on open standards or not, most projects would rather work on their project than run their infrastructure. And GitHub (like Sourceforge before it), has enabled many small projects to flourish because they don’t need to spend time on infrastructure. Imagine if every project needed to run it’s own issue tracker, code repository, etc. The barrier to entry would be too high.
Striking a balance
GitHub provides an instructive example. It uses an open, decentralized technology (git) and layers centralized services on top. Users can get the best of both worlds in this sense. Open purists may not find this acceptable, but I think a pragmatic view is more appropriate. If allowing some proprietary services enables a larger and more robust open software ecosystem, isn’t that worthwhile?
