We need reliability & choice. Let your camera be your competitive advantage, not your formats
We need reliability in the images WE record...we need to be sure we can still access/read/convert/process/print these images 50 yrs later.
We need choice & a free market. I don't necessarily want to use the camera maker's RAW processing s.w...which may disappear someday anyhow, or stop being available on my operating system of choice, etc. They shouldn't close-off the free-market of processing s.w.
Camera-makers should compete on the merits of their hardware, not use file-formats to seek competitive advantage or monopolies.
