I don't know. I think this will spur innovation that facebook couldn't possibly buy all of. People will be more likely to avoid building a core experience around a free service and instead either; innovate on their own and learn what is needed if it is really their dream or use an established open source platform if a sufficient solution exists. One downside to some open source projects is that they are meant to be flexible to a lot of use cases so you get a lot of subjective bloat with respect to your use case. But in the early stages, if the api is only a side show but main enabler to the key idea, it's still worth it to ignore the "bloat".

Our society/economy is currently not advanced enough to support free services nor are there many options to hide/divert costs sufficiently as not to matter. Eventually any free service must come to an end.
