Why is this so exceptional? What would we do if twitter folded tomorrow? things like this happen all the time. There is nothing special about it, except Wired wants to make money taking this tack.
I mean, it'd be nice if we could depend on things to be there forever and it'd be nice if companies shuttered gracefully, but it does not happen all the time.
What are they saying in essence? Don't depend on closed source services? Don't depend on non-creative commons Wired articles for your news as they may shut down one day? People make a calculus. This option is closed source, but offers this advantage. I know, as any business, they may disappear and I'm left holding the bag, but I'm willing to take that chance, given the advantages. This is also the case for open source software, but, yes, OSS has the advantage that someone with sufficient need and resources could resurrect the project.
Fine, they have a preference for open source. That's great. We could all hope all was open source but short of that, we use the tools that are available --with the understanding they could disappear tomorrow.
