I'm not sure I buy the absolute supremacy of open formats. They are good for emergency recovery (no depending on a company that just went kaput) but they often lack momentum. MP3 is not an open format, but I would argue it's one of the best choices for storing your music because it is everywhere. MP4 hasn't gained quite the same traction yet but we're headed that way.
Now, if you are a savvy programmer and you archive the (open) OGG spec, you could argue that you can write your own custom OGG -> MP2073 encoder at any time to recover your ancient music. But that's not most of us.
Another example that comes to mind is the many MS Office replacements I've used over the years. I have a small trove of old documents in old open formats used by StarOffice, OpenOffice, & others that are a pain in the butt to access and don't always render correctly, while my ancient .doc files from twenty years ago still open in two clicks.
I'd consider mp3 an open format, and office documents are an exception. MS has gone above and beyond for it to work. There is thousands of dead formats out there unfortunately.
