Counter-counterpoint would be, Apple becomes a customer of the API, and then someone else (Google, Facebook, whoever) buys Dark Sky and Apple has to scramble.

I'm bitter too, I build my own local/remote weather station at home (several Raspberry Pi's, an Arduino with a custom shield, and 15k lines of Python), which uses Dark Sky's API as one of its data sources. This means I have a year or so to find a new data source and rewrite a bunch of code (and no source is going to give me exactly the same data from the same sensors, so my 3-4 years of historical data is going to have a definite before/after cutoff in it).
