If Twitter's business is threatened by third-party apps, why not charge for an API license? I also can't quite understand why developers expect a free API from services like Twitter and then complain when something changes?
What is the business advantage of Twitter (or Facebook, or what-have-you) releasing a free, public API to anyone who asks, and how did they plan to monetize it when it got popular? You can't build your business model around "here, use my service for free" and not have a plan how to convert either the users of the 3rd party developers' software or the 3rd party developers themselves into paying customers (or monetize on that somehow, i.e. mining data, selling ads, etc). Maybe I'm just being naive -- I honestly don't have much experience dealing with these sorts of things, so I would love it if someone could break it down.
I agree with you. Google's model is pretty good with most of their 25+ APIs having free tiers. Free is nice but being in a real business relationship feels better to me because it is more likely to be sustainable. Microsoft's API marketplace has the same solid sustainable feeling.
If a business idea requires free use of other people's services then think of another idea.
