I believe they're talking about the Facebook required to signup for Spotify which is causing a lot of controversy lately.

Yes, that is correct. I could however just look at it as paying $10/month for a service that I know will only be around for the short term, or around in the short term in a format that I like to consume but will change dramatically and without notice in the near future due to the magical* whims of some product lead over at the Parent Company (Fb).

* I'd like to know what sort of of process a product person goes through whence writing stories or making suggestions for a product. Do they eval their own ignorance, stupidity, pettiness and laziness, choose two for average and proceed to operate forward using only those two qualities backed up by a mid-ranked college's beer-stained diploma?

tl;dr: even Angry Birds didn't sell out sooner.
