Yahoo Music to close down: DRM matters

Yahoo suddenly announced to its clients that its music store was about to close down. Nothing much serious except their DRM licenses management servers will switch off this september 30.
This deadline passed, the purchased music will be unusable unless one was cautious enough to burn CD's out of it. If you do so, be aware that the double encoding from AIFF and then to MP3 or AAC will cause quality loss. .
It is the third time this problem is raised after Sony and Microsoft online stores shut down. Once again to notice that the DRM are only a bother for honest people who didn't want to steal music but end up swindled, not to say robbed.
It's about time that the market players who sell protected Music commit themselves to carry on their license contract service at least for X years, for people to decide whether or not to buy regarding if that length of time is enough to ensure them a sufficient investment.
Banks and other financial companies require guaranties for them to continue to exist. It should be just the same for online music stores clients.
Easiest way would be to get rid of the protections once for all but if that's the way to follow, why not following through when a significant amount of music is still DRM protected on the iTunes Store?
