That's one (very pro-Apple) way to see it. Here's another. Apple markets Music hard and maybe turns a lot of people onto streaming music that have never been interested before. The free trial will let them judge it for themselves and see how much they like it. At the end of their free trial, they can continue with Apple for $10/month or switch to Spotify for $0/month. Some chunk of them will probably want to switch to free for a fairly similar offering.
It could be a disaster scenario or it could be a huge, rich company marketing streaming to the masses beyond what Spotify can afford and then at least a chunk of those masses choosing free over $10/month when the time comes to pay Apple or don't pay Spotify.
Also there are 2 very different business objectives underpinning all of this. We're keying a lot of differentiation around model profitability because Apple making even more money is important to us consumers(???). However, Spotify is a PRIVATE company. They don't have obligations to public shareholders like Apple. As such, their business objective is not necessarily maximize short-term profitability but to build up their business value for an eventual IPO. This is very much like Facebook in pre-IPO mode. Just like Facebook, growing the numbers of subscribers even if there is a financial loss appears to boost the perceived value in an IPO. Spotify's owners will get very, very RICH when it goes public. Apple is already very, very RICH.
Our sentiment here- always being so pro-Apple- seems to be in a Spotify is now an enemy because Apple has something that directly competes with them. But if one can set aside their Apple-bias for a moment, any negative wishes for Spotify is simply wishing away a pretty comparable streaming music service that is available for as little as free or free* so that a very, very profitable company can make even more money. How do we consumers win by wishing away options that would cost us less than Apple's offering? Isn't it better (for us consumers but not necessarily Apple Inc.) to at least have options?
If Apple's offering is superior to Spotify, Pandora, etc, it should win on it's own merits. All this fault finding with Spotify, Pandora, etc as part of rationalizing Apple's new offering is both par for the course and mostly about trying to trample the relatively small competitors to further enrich the giant. If Apple's offering is worth $10/month, it doesn't need us to prop it up with spin or competitor beat-downs. And if it's not worth $10/month, it certainly is good that those who want some kind of streaming music service have more choices than just one.
