What is the real issue?
I am definitively for an open RAW format, or standard, but there are a couple of things I do not really understand. What is the real issue/surpise/betrayal?
Any computer file format, or any data format for that matter, is by nature a transient format. As technology evolves some formats will die, others will be adopted. That is just the way it is.
No matter how much you loved 8-tracks, all your Lynerd Skynerd tapes went the way of the Do-Do, unless you care for them enough to keep the old AMPEX dinosaur working. The same thing happened to all the Spy vs. Spy video games that I had on 5.25 floppy disks. I know that probably one day I'll have to keep some old software running just to have access to all my RAW files, and I have no problem with that issue.
