Apple stepped on a lot of toes at WWDC. Or at least it threatened to. Some start-ups whose business models sit directly in Cupertino’s path issued some pretty brave statements this week.
Rdio, which offers a live-streaming music service in the space Apple Music plans to occupy, put out a cheeky homage to the gauntlet Apple’s threw down in 1991 to IBM:
“Welcome, Apple. Seriously. Welcome to the most exciting and important frontier since the digital music revolution began 16 years ago.” (The Next Web)
Flipboard, whose magazine-like mobile app could have been the template for Apple’s new News service, struck a similar note:
“What Apple was showing is something that we actually shipped five years ago,” said CEO Mike McCue on a BBB podcast.
Rdio seems to have forgotten that Apple got bulldozed by IBM. And Flipboard wasn’t exactly setting the publishing world on fire before Apple demoed News.
Daniel Ek, co-founder of Spotify, Europe’s leading music streaming service, was more circumspect. And realistic. On Monday he responded to the advent of Apple Music with a two-word tweet: “Oh, ok.”
Later he told a Swedish magazine (as translated by Reuters):
“To me, it is enough to be among the top three.”
