Thirdly: As most of you know, Microsoft employ a strategy of making their software deliberately obsolete - they make it forwrd compatible, but not backward compatible. With the laws of the DMCA, it will soon be illegal to try to make a software product that is compatible with another programs file types (for example, take the many office applications there are for Linux which have had some success in translating their arcane file formats).
This has the effect of killing any competition in the water - since you're not allowed to make your new product compatible with any of the others, no-one will use it. And eventually people will give up using any of the others instead, since no-one else can read their documents. So the entire world will be left with one choice only for software - Microsoft.
If software and car business were the same...
software manufactures were forced to use file formats defined bye the ISO, like car manufactures have to for the engine controling computers interface to the display system used in the garage. So that not only the special garage under contract with a manufacturer can use that information.
Also, what do I care if in the US some microsoft file formats are copyrighted? Or something like the compression algorithm used for GIF? - Not at all, because that's only a problem in the US (1/25th of earths population).
